Hotels.com: Book Hotels and Earn One Free Night for Every Ten You Book

Hotels.com is a hotel booking site that offers one of the most straightforward loyalty programs in travel: for every ten nights you book and stay at a hotel through Hotels.com, you earn a free night's stay. The reward is now delivered through the One Key program, which also connects with Expedia and Vrbo under the same account.

The value of Hotels.com is in its massive inventory. You can find everything from budget motels to luxury resorts, and the site makes it easy to compare prices side by side. Guest reviews are prominently displayed, so you can quickly see what other travelers thought before making a decision.

One feature worth knowing about is the "Secret Prices" program. When you sign in to your Hotels.com account and are a member of the One Key rewards program, you get access to discounted rates that are not visible to guests who are browsing without an account. The discounts are often 10 to 15 percent off the displayed price.

Hotels.com also has a price-match guarantee: if you find a lower price for the same hotel and room type within 24 hours of booking, they will refund the difference. This makes it worth doing a quick comparison check after you complete a reservation.

The Hotels.com mobile app is reliable and well-designed. It stores all your bookings, displays check-in instructions, and lets you manage cancellations or changes without calling customer service. For frequent hotel guests, the combination of the rewards program and secret prices makes Hotels.com a consistently good choice.
