For about fifteen years, Hotels.com had one reason to exist that nobody could copy cleanly: stay ten nights, get one free, at roughly the average value of the ten. No points, no transfer charts, no devaluation cycle. Then Expedia Group folded the brand into One Key, replaced the stamps with OneKeyCash, and the reason to use Hotels.com largely disappeared.
In 2026 the stamps came back. Hotels.com has broken out of the unified One Key earning structure and returned to its ten-stamp reward night. That is the single most important fact about this platform and it moves our score by more than a point.
What the stamps are worth
The arithmetic is genuinely simple, which is the point. Ten qualifying nights earn ten stamps; the stamps convert into one reward night valued at the average nightly rate of the ten that earned it. Stay ten nights averaging €120 and you have a €120 night to spend.
That works out at roughly a 9% return on qualifying spend — better than most credit-card travel earn rates and dramatically better than the sub-2% that OneKeyCash typically returns. It is also comprehensible in a way that airline-style points never are, which matters more than enthusiasts admit.
The exclusions are where it gets less tidy. Not every rate qualifies, prepaid third-party inventory sometimes does not count, and a night booked with a reward night does not itself earn a stamp. The rules are published, but they are published in the place people do not read.
What One Key took and did not give back
The other 2026 change is a straight loss. Expedia and Hotels.com both scrapped the Hotel Price Guarantee — the mechanism that refunded the difference if you found the same room cheaper elsewhere after booking. Nothing replaced it. Whatever you thought that guarantee was worth in practice (in our experience, not much: the claim conditions were narrow), removing it while the rest of the industry keeps some form of price promise is a step backwards.
One Key earning changes that took effect in July 2026 also introduced tier-based rates and removed earning on flight bookings entirely. Hotels.com's departure from that structure insulates it from most of this, but if you are booking a package with a flight through the Expedia ecosystem, the earn now applies only to the non-flight elements.
The site itself
Stripped of the loyalty question, Hotels.com is a competent, unexciting Expedia Group front end. Chain inventory is comprehensive. Confirmations are reliable. The map view is good. The interface is noticeably less shouty than Booking.com — fewer countdown timers, fewer claims about how many people are looking at this room — which is worth something on its own.
Independent properties are the weak spot. In the same small-town test searches where Booking.com returned a handful of guesthouses, Hotels.com returned chain hotels twenty minutes away or nothing at all. This is a platform for places that have a brand behind them.
The other structural oddity: prices on Hotels.com and Expedia.com are frequently identical, because they are the same inventory sold by the same company. Checking both is wasted effort. Pick the one whose reward you actually want.
Who it is for
The maths decides this. If you will book ten or more paid hotel nights in a year and most of them are at chain properties, the reward night is free money and Hotels.com deserves to be your default. If you stay four nights a year, or you mostly book small independents, the stamps will never mature and you are using a slightly worse Booking.com.
There is a middle case worth naming: business travellers who cannot use a company's preferred booking tool and are paying personally. Ten qualifying nights arrives faster than you think, and the reward night has no blackout-date behaviour to plan around.
Making the stamps actually mature
The scheme only works if you concentrate bookings, and a few rules make that worthwhile rather than costly.
Check the rate qualifies. Not every rate earns a stamp, and third-party prepaid inventory sometimes does not. The listing states it; people do not read it.
Do not chase stamps at a price premium. A night that costs €40 more to earn a stamp worth €12 of eventual reward is a bad trade. The reward is roughly nine per cent; pay no more than that for the privilege.
Watch the expiry. Stamps have a validity period. Nine stamps that lapse before the tenth is the specific failure this scheme produces, and it is avoidable by checking the balance before booking elsewhere.
Use the reward night on an expensive night. The reward is valued at the average of the ten that earned it, so redeeming against a cheap night wastes the difference while redeeming against an expensive one requires a top-up. The sweet spot is a night close to your average.
Where it sits for a business traveller
For anyone booking their own hotel nights on business, the stamp scheme is quietly one of the better returns available, because ten qualifying nights arrives in a couple of months rather than a couple of years.
The constraint is that many corporate travel policies mandate a booking tool, and reward-earning through a personal account on a company booking is a policy question rather than a travel one. Where it is permitted, Hotels.com is a better personal return than almost any hotel chain's own entry-level loyalty tier.
The verdict
Hotels.com is a one-feature platform, and in 2026 it got its feature back. That is enough to make it worth using for frequent bookers and not enough to recommend to anyone else. The removal of the price guarantee and the thin independent inventory keep it below its stablemates in this ranking; the honesty and simplicity of the stamp scheme keep it comfortably above the opaque-rate sites further down.
