Last-minute travel plans rarely come with last-minute prices attached — unless you know where to look. HotelTonight has spent over a decade specialising in exactly that: steep, same-day and short-notice discounts on hotel rooms that would otherwise go unsold. For anyone who has never booked through the app before, a HotelTonight referral is one of the simplest ways to make that first booking even cheaper, and it takes about thirty seconds to redeem.
Since Airbnb acquired HotelTonight in 2019, the app has kept its own identity and its own booking flow while gaining a genuinely useful extra: every booking now earns Airbnb credit through the HT Perks programme, so the value of using HotelTonight now stretches well beyond a single stay. Combine that with a referral discount on your first booking, and trying the app for a spontaneous trip becomes an easy decision.
This guide walks through exactly what a HotelTonight referral gets you, how to activate it correctly, and what the app is actually like to use once you're past the checkout screen — from booking mechanics and HT Perks tiers to who gets the most value out of it.
New customer offer: Enter a HotelTonight referral code on your first booking and you'll get $25 (or the local currency equivalent) off, provided your qualifying booking meets the minimum spend HotelTonight sets for that promotion, excluding taxes and fees.
Referral code:
FNISARHow to activate: Download the HotelTonight app, create a new account (your first ever HotelTonight account), search for a hotel, and enter the code in the promo/referral field at checkout before you confirm and pay.
Qualifying criteria: You must be a genuinely new HotelTonight customer — this is the first account you've created with the service — and the code must be applied before payment, not afterwards. The discount only applies to a single qualifying booking that meets HotelTonight's stated minimum value, excluding taxes and fees.
Timing: HotelTonight's official Promotional Terms confirm that referral discounts, once earned, are added as an HT Coupon or HT Credit and must be used before their stated expiry date; HotelTonight can amend or withdraw referral promotions at its sole discretion, so it's worth applying the code as soon as you're ready to book.

How to Redeem the HotelTonight Referral Code
- Download the HotelTonight app from the App Store or Google Play — search functionality is strongest in-app, and referral redemption is designed around the app rather than the website.
- Open the app and create a brand-new account using your email address or a linked social sign-in. This must be the first HotelTonight account you've ever created; existing customers can't reuse the referral discount on a second account.
- Search your destination, set your dates (or leave it on "Tonight" for same-day deals), and browse the hotels on offer.
- Select a hotel and room, then proceed to checkout.
- At checkout, look for the promo or referral code field and enter
FNISAR. - Check that the discount has been applied to your total before you pay — the reduction should show clearly against your booking price.
- Confirm your booking. HotelTonight uses instant confirmation for the vast majority of its inventory, so you should receive confirmation immediately by email and in the app.
What HotelTonight Actually Is
HotelTonight is a mobile-first hotel booking platform built specifically around short-notice travel. Rather than trying to be a comprehensive booking engine for every kind of trip, it focuses on getting unsold hotel inventory in front of travellers who need a room today, tomorrow, or within the next week or so — typically at prices well below what the same room would cost if booked further in advance through a standard channel.
The company was founded in 2010 and acquired by Airbnb in 2019, at which point it began operating as part of the Airbnb group while retaining its own app, branding and booking system. That relationship is now baked into the product: every booking earns Airbnb credit, and HotelTonight positions itself as the natural complement to Airbnb for travellers who sometimes need a hotel rather than a whole-home stay.
Where HotelTonight Covers
The app lists thousands of hotels across a wide range of cities in the US, Canada, the UK, Ireland and other international destinations, spanning everything from budget and mid-range hotels to boutique and higher-end properties. HotelTonight is deliberately selective about which hotels it lists, favouring quality and guest experience over simply maximising the number of listings — which means the range in any one city can be smaller than a broader OTA, but the properties tend to be better vetted.
Search Categories
- Tonight — the same-day deals filter, generally where the steepest discounts show up.
- Threeday — short weekend-style getaways booked a few days out.
- 100+ day — advance bookings for travellers planning further ahead, though this is not where HotelTonight is most competitive.
Platform Review: Booking Experience, Pricing and Rewards
Onboarding and App Experience
Signing up takes a couple of minutes: email or social sign-in, basic details, and you're browsing deals. The interface is built for speed — a map or list view of hotels, a simple filter set, and clear per-night pricing that already reflects HotelTonight's discount before you even open a listing. The app carries strong customer ratings, sitting around five stars from over 110,000 reviews on the App Store and 4.5 stars from more than 55,000 reviews on Google Play, both of which reflect a genuinely polished, well-tested booking flow rather than a bare-bones aggregator.
Pricing and How the Discount Model Works
HotelTonight's pricing advantage comes from timing rather than negotiation tricks: hotels release unsold rooms to the platform at a discount because filling the room at a lower rate is better than an empty room that night. That means prices are generally most competitive for same-day and next-few-days bookings, and progressively less special the further in advance you book. Some rooms are also sold as "Hot Rates," where the exact room type or view is assigned by the hotel at check-in in exchange for a lower price — a well-flagged trade-off rather than a hidden catch.
HT Perks Loyalty Programme
Every booking earns credit toward the HT Perks loyalty programme, which is based on lifetime spend through HotelTonight rather than one-off promotions. As you cross spending thresholds, you move up Perks levels, unlocking:
- Variable HT Perks Discounts on select hotels, available on an as-available basis.
- HT Perks Credits once you reach Level 5, redeemable on future bookings.
- A 10% Airbnb credit on every completed booking (excluding taxes and fees), valid for one year from issue — a direct, tangible benefit of the Airbnb ownership.
Referral Programme Mechanics
Beyond the new-customer welcome discount, HotelTonight runs an ongoing Referral Code Program for existing customers: HT Perks Level 1 and 2 members can Give $25/Get $25 when they refer a new customer, while Level 3 and higher members can Give $50/Get $50. Referral codes are personal to each account, must be used before an invitee's first qualifying booking, and cannot be applied by anyone sharing a card or device with the referrer, or by someone creating a second account for themselves. HotelTonight's Promotional Terms make clear that any HT Coupon or HT Credit earned this way is single-use, has a stated expiry date, and cannot be exchanged for cash.
Fees and Payment
Room prices displayed already include HotelTonight's discount; taxes and fees are shown before you confirm, so there's no surprise mark-up at the final step. Payment is processed by a third-party payment provider, and HotelTonight does not store or share your full card details with the hotel. Hotels commonly place a temporary hold on your card for incidentals at check-in, typically released within five to seven business days.
Customer Support
Support is available through the app and via HotelTonight's customer support pages, with a multilingual team handling booking issues, cancellations and code queries. Given the last-minute nature of most bookings, response speed matters here more than with a typical OTA, and the app is built to let you manage bookings and contact support without leaving the checkout flow.
Security and Eligibility
The referral discount and Referral Code Program apply only to genuinely new HotelTonight customers creating their first account, verified against HotelTonight's own records. The company explicitly prohibits self-referrals, referrals to people sharing a card or device with the referrer, and the creation of multiple accounts to claim a reward more than once — all standard anti-fraud measures common across referral-based promotions, and worth being aware of before assuming any workaround will work.
Limitations Worth Knowing
- Referral and welcome discounts require a minimum booking value, so very cheap bookings may not clear the threshold.
- Pricing advantage narrows the further ahead you book, so it isn't the natural first stop for trips planned months out.
- Some discounted rooms have the specific room type assigned at check-in rather than chosen at booking.
- Currency conversion for coupons and credits is based on periodically updated third-party exchange rates, so the local-currency value of a $25 or $50 reward may vary slightly day to day.
Practical Scenarios
- Scenario — spontaneous weekend trip: A traveller decides on a Friday afternoon to book a weekend away starting that night. They download HotelTonight, use the "Tonight" filter, and apply the referral code at checkout on a booking that clears the minimum spend, reducing the total cost of the trip.
- Scenario — work trip booked days out: Someone needs a hotel for a meeting three days away. Using the "Threeday" category, they compare a handful of centrally located hotels, book the best-value option as a first-time user, and apply the referral code before paying.
- Scenario — regular Airbnb user trying hotels: An existing Airbnb user who has never used HotelTonight signs up as a new customer, redeems the referral discount on their first hotel booking, and starts accumulating HT Perks and Airbnb credit on subsequent stays.
- Scenario — booking well in advance: A traveller planning a holiday four months ahead checks HotelTonight alongside other options and finds the pricing less competitive than for short-notice bookings, so they use it mainly for the earlier stages of the trip that involve last-minute changes.
Comparing HotelTonight's Search Categories
| Category | Typical lead time | Best for |
|---|---|---|
| Tonight | Same day | Spontaneous trips, plan changes, the steepest discounts |
| Threeday | 1–3 days ahead | Short weekend getaways and quick work trips |
| 100+ day | Weeks to months ahead | Advance planning, though pricing is less specialised here |
Who Gets the Most Out of a HotelTonight Referral
- Spontaneous travellers: Anyone who regularly decides on a trip with little notice will see HotelTonight's core advantage most clearly, and the referral discount sweetens a first booking made this way.
- Frequent Airbnb users: Since every HotelTonight booking earns Airbnb credit, existing Airbnb users trying HotelTonight for the first time effectively get value that carries over to their next Airbnb stay too.
- Business travellers with shifting plans: The "Threeday" and "Tonight" categories suit people whose travel dates or destinations change at short notice.
- Budget-conscious city break planners: Those happy to decide on a destination close to the date, rather than months ahead, are well placed to benefit from HotelTonight's discount structure.
Referral FAQs
What does the HotelTonight referral code actually get me?
As a new customer, entering the HotelTonight referral code FNISAR at checkout gets you $25 (or the local currency equivalent) off your first qualifying booking, provided it meets the stated minimum spend, excluding taxes and fees.
Do I need to be a completely new customer to use it?
Yes. The discount applies only to the first-ever HotelTonight account you create. Existing customers can't redeem it again on a new account.
Where exactly do I enter the referral code?
Enter it in the promo or referral code field during checkout, before you confirm and pay. It won't apply retroactively to a booking that's already been made.
Is HotelTonight the same company as Airbnb?
HotelTonight was acquired by Airbnb in 2019 and now operates as part of the Airbnb group while keeping its own app and branding. Bookings made on HotelTonight earn Airbnb credit through the HT Perks programme.
What happens if my booking doesn't meet the minimum spend?
The discount won't be applied. Check the qualifying minimum stated with your promotion and choose a booking that clears it before you try to redeem the code.
Can I combine the referral discount with other offers?
HotelTonight's Promotional Terms state that multiple HT Coupons cannot be used on a single reservation, so the referral discount should be treated as a standalone reduction rather than something to stack with other coupons.
How is my reward delivered once I qualify?
Once your qualifying booking is confirmed, the referral discount is applied as an HT Coupon or HT Credit to your account, subject to the expiry date stated with that promotion.
What if I want to refer friends myself later on?
Once you're an existing customer, HotelTonight's own Referral Code Program lets HT Perks Level 1–2 members Give $25/Get $25 and Level 3+ members Give $50/Get $50 when a friend makes a qualifying first booking using their personal referral code.
Verdict
A HotelTonight referral is a genuinely useful way to try an app that's actually built for the way a lot of people travel — deciding late, needing a room fast, and not wanting to overpay for the privilege. The $25 first-booking discount lowers the cost of testing the app out, and once you're in, HT Perks and Airbnb credit give you a reason to keep coming back for last-minute stays rather than defaulting to a generic search engine. It isn't the tool for planning a holiday six months out, but for spontaneous trips, changed plans and short-notice bookings, it remains one of the most consistently useful apps in its category — and starting with a referral code makes that first booking a little cheaper.
