About HotelTonight

HotelTonight is a hotel-booking service focused on finding and reserving rooms at selected hotels, resorts, bed-and-breakfasts and similar accommodation. Its official homepage positions the service around last-minute deals, but it also says customers can book tonight and beyond. The app and website show available properties, dates, room information, prices and booking conditions, while the underlying accommodation contract is made directly between the guest and the hotel or other supplier. HotelTonight facilitates the reservation and payment process; it does not own or manage the accommodation. The platform is especially useful when plans change, when you need a room close to the current location, or when you want to compare participating hotels with short-lead availability. Availability, price, room type, cancellation terms, taxes and on-site charges are property- and destination-specific. HotelTonight’s FAQ says stays may be bookable up to 100 days ahead, for up to 14 nights, and that a room can generally be booked until 2am on the first night in the hotel’s local time. Search results can also permit up to four rooms in one booking. The app may offer location-based discovery and app-only or account-based features, so checking the live listing rather than relying on a general advertising claim is important.

Get £20 Off with HotelTonight

Stored referral offer: £20 Off. Stored referral code/link label: FNISAR. Exact referral URL: . The URL is intentionally blank because that is the stored referral fact; do not substitute another URL. The code/label FNISAR is the stored route to try, subject to HotelTonight accepting it and displaying the expected offer at redemption. Listing checked: 26 May 2026. Category: Money Saving. Important verification note: HotelTonight’s currently published official FAQ and Promotional Programs terms describe referral examples in US-dollar equivalents: a Level 1 or 2 member’s Give $25/Get $25 promotion requires a new customer’s qualifying first booking of at least $135 excluding taxes and fees, while the Level 3+ invitee arrangement is described separately and can involve up to $50 or 20% of the first booking. Those official pages do not independently confirm the stored £20 amount or the label FNISAR. Currency, market, account status, promotion cohort and campaign timing can change the displayed result. Therefore, treat £20 Off as the supplied listing fact, not as a guarantee: confirm the amount, minimum spend, expiry and eligible booking in the app or at checkout before paying.

How to claim the offer

  1. 1Create or open one HotelTonight account using accurate current details. HotelTonight’s Terms say an account may be required for some features and prohibit registering multiple accounts, transferring an account, or using another person’s account.
  2. 2Use the stored referral route: enter the code/label FNISAR where HotelTonight provides a Promo code or Redeem control. The exact referral URL is blank in the stored record, so no replacement link is supplied. In the app, the official FAQ says a code can be entered by tapping Promo code at checkout, or saved in the account profile by tapping Redeem next to Promo Code.
  3. 3Search for the intended destination and dates, then open an eligible property. Review the room rate, total price, taxes and fees, room type, occupancy, check-in time, hotel-specific rules and cancellation wording. A referral code can be accepted yet still fail to apply if the selected booking does not satisfy the campaign’s qualifying conditions.
  4. 4Before confirmation, enter FNISAR exactly as stored, with matching capitalization and no extra spaces. Look for a visible discount, coupon or credit line and check that the total changes. Do not assume a code has worked merely because it was saved to the account.
  5. 5Check the qualifying-price calculation. HotelTonight’s published referral examples measure minimum booking value excluding taxes and fees. Compare the promotion’s displayed threshold with the room-rate subtotal, not only the final amount charged; also check whether the promotion is limited by dates, destination, inventory, account, device or payment method.
  6. 6Complete the booking only after the offer is visible and the final total is acceptable. HotelTonight charges the payment method for the reservation price shown at checkout; incidentals, upgrades, resort fees or other amounts due at the property may remain payable directly to the hotel.
  7. 7Save the confirmation and inspect the Credits or account area for the coupon or credit, its expiry date and any remaining conditions. HotelTonight says credits are used in expiry order and all promotional credits have an expiration date. If the code produces an error, capture the message and contact official customer support rather than creating another account.

Your referral benefit

The stated saving is £20 Off on a qualifying HotelTonight booking when the stored referral route FNISAR is accepted. The practical value depends on the eligible room-rate subtotal, currency conversion, taxes and fees, and whether the promotion is still live for the customer’s market and account. A discount is not necessarily £20 off the complete card charge: HotelTonight’s official referral terms describe thresholds and promotional values excluding taxes and fees, and its Terms say guests can also owe incidentals, upgrades, resort fees or other on-site charges. The strongest use case is a booking whose room-rate subtotal comfortably exceeds the displayed threshold, allowing the discount to be applied without leaving the booking ineligible. Check the final checkout breakdown rather than estimating from a headline price.

Before you claim

  • Confirm that the code/label is exactly FNISAR. The stored exact referral URL is blank, so this article deliberately does not invent or replace a URL.
  • Confirm the offer shown in the live account is £20 Off, because the supplied listing amount conflicts with the current official pages’ published $25/$50 referral examples. Record the currency and displayed value before booking.
  • Confirm that the account is genuinely new if the promotion requires a first booking. HotelTonight’s FAQ says first-time promotions may be rejected when the same account, device or payment method has previously been used to book.
  • Confirm the qualifying minimum and calculate it excluding taxes and fees. The current official Give $25/Get $25 terms cite a minimum of $135 or equivalent for the invitee’s first qualifying booking; do not apply that figure automatically to the stored £20 offer unless checkout shows it.
  • Confirm that the code has not expired, reached its claim limit, already been redeemed, or been entered incorrectly. HotelTonight lists each as a possible reason for an error.
  • Confirm the code is not being combined with another coupon or promotion. HotelTonight’s FAQ says promotions cannot be combined and a promo code can only be redeemed once.
  • Confirm the referral relationship is legitimate and personal. Published terms prohibit self-referrals, same-credit-card or same-mobile-device referrals, multiple-account manipulation, commercial distribution, coupon-site distribution and search-engine marketing.
  • Confirm credit expiry in the Credits area. The current Promotional Programs terms say referral-program coupons or credits expire 120 days from issue unless the specific promotion says otherwise; the promotion shown in the user’s account controls if different.
  • Confirm cancellation terms before payment. HotelTonight says most rooms are non-refundable, non-cancellable, non-transferable and non-modifiable unless different terms appear at checkout; refunds and changes may be at the hotel’s discretion.
  • Confirm hotel-specific requirements such as minimum age, identification, payment card, occupancy, check-in time and incidentals. HotelTonight’s Terms make the guest responsible for reviewing supplier requirements.
  • Keep the receipt and booking confirmation. HotelTonight’s FAQ says a receipt can be accessed from Bookings and sent to the user, although it does not offer VAT or PDF receipts through that FAQ workflow.

HotelTonight referral questions

What is the HotelTonight referral offer listed here?

The stored listing says £20 Off, with FNISAR as the referral code/link label. The exact referral URL is blank and remains blank. HotelTonight’s official current pages show different example campaigns ($25 or $50 in the US terms), so verify the live amount and conditions in checkout before relying on the saving.

Where do I enter FNISAR?

HotelTonight’s FAQ says to tap Promo code at checkout and enter the code. It also says you can save a code for later from the account profile by tapping Redeem next to Promo Code. Enter FNISAR exactly as stored and confirm that a discount line appears.

Is £20 Off guaranteed?

No. It is the immutable stored offer fact for this listing, but official HotelTonight terms control the live promotion. The current published referral examples use dollar amounts and specific member levels, and they do not verify FNISAR or this exact £20 campaign. The app’s eligibility message and final checkout total are decisive.

Who can normally use a HotelTonight referral code?

For the published referral program, the invitee must create their first-ever HotelTonight account, use the personal referral code, make a qualifying booking and satisfy the promotion’s booking requirements. HotelTonight may reject a first-time offer if the account, device or payment method has already been used for a booking.

Does the minimum spend include taxes and fees?

HotelTonight’s published referral examples say the minimum booking value excludes taxes and fees. Check the specific offer displayed for FNISAR because the stored £20 campaign is not independently confirmed by those pages. Use the room-rate subtotal shown by HotelTonight, not just the card total.

Can I combine FNISAR with another coupon?

Usually not. HotelTonight’s FAQ says promotions cannot be combined, and a promo code can only be redeemed once. If checkout removes one offer when another is added, compare the resulting totals and keep the valid option that gives the better value.

When does a referral coupon or credit expire?

The current Promotional Programs terms say referral-program HT Coupons or HT Credits expire 120 days from the date issued unless the promotion states otherwise. The account’s Credits view and the offer’s own terms should be treated as the final expiry record.

Can I refer myself or use another account to get the discount?

No. HotelTonight’s published terms prohibit inviting yourself, using the same credit card or mobile device for the referral, creating multiple accounts and other manipulation. The service may suspend accounts, cancel bookings or revoke credits for suspected fraud or abuse.

Are HotelTonight bookings refundable after using the offer?

Often not. The FAQ says most rooms are non-refundable, non-cancellable, non-transferable and non-modifiable unless different terms are shown at checkout. Read the specific property’s cancellation rule before applying the code; a discount does not override the hotel’s policy.

Does the discount cover taxes, fees or hotel incidentals?

Do not assume so. Published referral thresholds and discounts are calculated excluding taxes and fees. HotelTonight’s Terms also say guests may owe incidentals, upgrades, resort fees or other charges directly to the hotel. Review the full checkout breakdown and the property’s ‘know before you go’ information.

How far ahead and how late can I book through HotelTonight?

The official FAQ says bookings can be available up to 100 days before check-in, stays can run up to 14 nights depending on availability, and booking can generally remain possible until 2am on the first night in the hotel’s local time. These are platform guidelines, not a guarantee for every property.

What should I do if FNISAR gives an error?

Check spelling, expiry, claim limits, prior redemption and qualifying dates, location and minimum spend. Also check whether the account, device or payment method has prior HotelTonight booking history. If the offer still appears eligible, contact HotelTonight support with the error and booking details; do not create a second account.

IG Index

£50–£1,000 Free Share

**Referral code/link:** Referral link **Referral URL:** https://refer.ig.com/faisaln-185 Use the URL exactly as shown, before starting the account application. On 12 October 2026, this supplied destination was reachable and redirected through IG’s referral tracking flow to an IG investment-account creation journey. It is therefore recorded as live, but a redirect alone cannot prove that every applicant will be accepted, tracked or paid. Keep a dated screenshot or confirmation showing that the referral route was used. IG’s current UK Refer a Friend page says that the invited person can receive a free share worth **£50–£1,000**. It says the share is selected from a list of eligible US companies, and gives examples such as Apple, NVIDIA and Amazon; those examples are not a promise of a particular company. The same page says the referrer receives £100 cash after a successful referral. That £100 is the referrer’s reward, not an additional £100 payment to the person using this entry. The public qualification sequence is specific: open a share-dealing account, ISA or SIPP through the referral link; invest at least £1,000 and place a first trade within 30 days; then keep an Average Invested Value of at least £1,000 for three months from the first investment. IG also says a W-8BEN form must be completed before the end of that three-month period in order to receive the US-share reward. The free share is credited to a GIA. Important details remain provider-confirmation points. The public referral page does not fully set out every residency, age, existing-customer, identity-verification, tax, account-approval, funding-source or promotion-stacking condition, nor does it explain the detailed calculation of Average Invested Value. It also says a referral can expire and that the qualifying steps must be completed in the required timeframe. Do not rely on another IG campaign page, a voucher code or a previous promotion’s terms as a substitute for this referral’s live terms. Ask IG to confirm personal eligibility, the applicable terms and whether another offer can be used at the same time before committing funds.

Avanti Travel Insurance

Up to 20% Off

**Reward recorded: Up to 20% Off.** This is the referral route recorded for **CLARE HUNT**. Use the referral page exactly as supplied: **https://avantitravelinsurance.mention-me.com/m/ol/df1jgetz-clare-hunt**. On the live Mention Me landing page checked for this record, the page says that Clare referred the visitor and asks for an email address to obtain a discount; it displays “up to 20% off” and also “20% OFF” wording. Avanti’s own referral terms describe the referred-friend reward as **up to 20% off the first policy**. Because the landing page and programme language are not a final price, verify the actual reduction in the quote basket before payment. The practical route is to open the exact link, provide the requested email address and use the discount code that is sent when buying online. Avanti’s referral page also says a visitor without a link can enter the referrer’s full name at checkout. The directory identifier is **CLARE HUNT**; do not change its spelling, replace it with another name, or assume that it is itself the final checkout campaign code. The programme appears to issue a separate code after the email step. According to Avanti’s published referral conditions, the referred customer must be a **new Avanti customer** and **over 18**. The discount is for the first policy, is issued for one month, applies only to the base premium, and does not reduce medical screening costs or optional extras where relevant. It cannot be combined with another discount code in the same order. It is not cash, a gift card for the buyer, a refund on an existing policy, a guarantee of cover, or a waiver of underwriting, medical declarations, policy excesses or exclusions. Avanti can vary the programme and can refuse a reward, so provider confirmation is still needed if the cart does not apply the expected reduction.

RAC Breakdown

£25 Amazon Voucher

This directory record is for RAC Breakdown and records the promotional benefit as a **£25 Amazon Voucher**. RAC’s own referral pages describe the reward as a £25 Amazon Gift Card. Their published headline is that, when an RAC member refers a friend and that friend joins, both people receive the Amazon reward. RAC also says a referrer can refer a maximum of 12 people. This record preserves that advertised referral proposition, but it is not a price reduction on a RAC policy and it does not promise a particular breakdown-cover level. **Code/link: Referral link** **Exact destination: https://refer.rac.co.uk/hayleyd-812** Use that destination exactly as written. No separate alphanumeric promo code has been supplied for this directory entry, so do not substitute a code found on another website, remove the identifying part of the address or assume that a general RAC checkout will retain the referral. The exact destination should be opened before starting the quote and the visitor should make sure the referral journey remains associated with the application through to the point RAC confirms it. The verifiable qualification currently available from RAC’s public referral wording is limited: the other person must join RAC through the referral arrangement. The full landing-page journey for this particular destination could not be read in an automated check on 15 October 2026. It redirected into RAC’s referral-entry route and then displayed an RAC access/temporary-problems response requiring JavaScript and cookies. That does not prove the referral is invalid, because RAC’s own live refer-a-friend pages still advertise the £25 reward, but it means the provider must confirm the link-specific eligibility conditions before a purchase. In particular, this record does **not** assume whether an existing RAC customer can qualify, whether a particular cover level, payment method, add-on, contract type or purchase channel is required, whether a policy must remain active for a period, whether the referral can be combined with another promotion, or how RAC detects a missed referral. Those conditions were not available from the exact destination during the check. Ask RAC to confirm them in writing or through the normal purchase journey before relying on the reward. No reward delivery time, email address, fulfilment partner process, expiry date or replacement procedure is stated in the accessible referral material reviewed for this entry. Do not treat the voucher as cash, a discount applied at checkout, a payment towards the RAC premium, a repair fund, insurance cover or a guarantee of future Amazon purchasing power. It is an advertised Amazon reward only after RAC regards the referral and joining event as qualifying. Amazon’s own gift-card conditions may also apply; RAC should confirm the current fulfilment details for this promotion.

Motorway

£50 Amazon Voucher

**Motorway referral offer: £50 Amazon Voucher.** The directory’s exact referral code/link is **Referral link**. Use this exact destination, without editing or substituting it: **https://motorway.mention-me.com/m/ol/ml8cwrmv-hayley-duster**. The live destination displayed a £50 Amazon.co.uk Gift Card reward for the referred seller when they sell their car with Motorway, and said that Hayley also receives a £50 reward. Motorway’s referral help describes the same arrangement as both people receiving a £50 Amazon.co.uk Gift Card, a £100 total split, after the referred friend completes a qualifying sale and the car is collected. For the person using this directory entry, the reward is therefore a **£50 Amazon Voucher**, described by Motorway as an Amazon.co.uk Gift Card. It is not cash, not a discount off the car-sale service fee, not a payment in advance and not a guaranteed supplement to a vehicle offer. The referral landing page says Amazon restrictions apply; readers should review Amazon’s applicable gift-card terms before relying on a particular use. Motorway says the referred customer must reach Motorway through the unique Mention Me referral link, not merely type an incomplete or altered address. It also says the referral cannot be added retrospectively where a person has already sold, or is already selling, without the link. A qualifying car must be eligible for Motorway’s online daily sale to its nationwide dealer network. Motorway says it indicates this when a customer values the car; its help notes that eligibility criteria relate to model, age and mileage. A sale routed through CarTakeBack or TheCarBuyingGroup rather than the online daily dealer sale is specifically excluded from the referral scheme. The referred customer must not have sold a vehicle with Motorway in the preceding 12 months and must not already have been referred by someone else. Motorway also says anti-abuse controls apply. These conditions are provider-controlled and can depend on the customer’s sale history, their link tracking and the eventual sale route, so this directory record cannot determine eligibility in advance. If any point is unclear, obtain confirmation from Motorway before committing to a sale. The destination was accessible at the recorded check, but the offer is marked as requiring provider confirmation because eligibility and fulfilment remain Motorway’s decision.

Super.com

10% off

This directory record preserves the exact referral code **J71527** and the exact referral destination **https://super.com/**. Its recorded reward is **10% off**. The live referral listing for this code describes it as 10% off a new customer’s first eligible hotel booking, subject to the offer and booking terms displayed by Super.com. Use that as the recorded promotion, not as a promise that it will apply to every account, room, property, date or part of a price. There is an important qualification to check before spending money. Super.com’s official referral guide currently explains the general programme differently: it says the new person should be someone who has not signed up, and that once they create an account and book a hotel, each person earns 10% off their **next** booking. The official guide does not name J71527 or confirm that it is currently linked to the first-booking version stated on the directory listing. The official Terms also say that rewards may be promotional credit or another method chosen by Super.com; their amount, any cash redemption and the precise actions required may vary. Super.com can change, add to or terminate referral programmes, and can remove rewards for abuse, misuse or fraud. Accordingly, enter **J71527** only where Super.com expressly presents a referral, invite or promotion field, and rely only on the offer text and price breakdown shown in the account or at checkout. Provider confirmation is needed for the exact qualification trigger, eligible hotel/rate scope, any cap, expiry, geographical availability, whether the discount is applied immediately or later, and whether taxes or other booking components are included. Do not create duplicate accounts or try to apply the code retrospectively: neither action is established as permitted, and the published Terms allow Super.com to decline or revoke rewards. This promotion is not stated to be cash, a transferable asset, a guarantee of the lowest hotel price, a membership fee waiver, a hotel reservation, or a refund entitlement.

Seatfrog

Upgrade Discount

**Seatfrog referral: £5 off a first eligible First Class upgrade.** Use the exact referral link **https://seatfrog.mention-me.com/m/ol/oe3lraqz-sharon-bal**. The referral code/name recorded for this offer is **Sharon Bal**. The live landing page for that exact link says that Sharon has saved the recipient £5 off their first upgrade to First Class and asks for an email address so a £5 voucher can be emailed. Do not alter the link, shorten it, or replace the recorded code/name with a different one. The offer should be treated as a referral voucher for a new customer’s first eligible upgrade, not as a general price reduction on all Seatfrog products. Seatfrog’s referral help says referred customers must be new and rewards apply to first-time purchases; the landing page is more specific about a first First Class upgrade. Before paying, read the wording displayed with the voucher and at checkout, because the provider says referral offers can change. The record does not establish the voucher’s expiry date, an eligible operator list, a minimum spend, whether it can cover any booking fee, or every excluded upgrade type. Provider confirmation is needed for any of those points if they matter to the trip. The £5 is an **upgrade discount**, not cash, a rail ticket, a fare quote, a guaranteed First Class seat, a winning auction bid, a Railcard discount, compensation for disruption, or a promise that food, a particular seat or other operator amenity will be available. It does not remove the need to hold a valid underlying ticket for the exact train. It also should not be read as a promise that an upgrade will be displayed, that a selected operator will participate, or that the final total will be £5: the app must show the actual eligible upgrade and checkout total.
