Booking.com wins for most European travellers — the larger selection (28 million+ listings versus Hotels.com's smaller inventory), superior search interface with map views and neighbourhood scores, and the Genius programme providing immediate 10-20% discounts after just 2-5 bookings make it the default choice. Hotels.com is better for travellers already in the Expedia ecosystem who book flights, hotels, and car rentals together, earning One Key points across all three platforms. The package deals bundling hotels with flights can save 10-30% on the combined booking. For any specific booking, always check three places: Booking.com for the widest selection, Hotels.com for potential bundle savings, and the hotel's own website for direct-booking perks like free breakfast, room upgrades, or full hotel loyalty points. Direct booking prices match OTA prices 80% of the time, and the added perks tip the balance. Remember that the cheapest displayed rate on both OTAs is often non-refundable — always compare flexible rates for a fair assessment.
Booking.com and Hotels.com together account for over 60% of online hotel bookings in Europe, processing hundreds of millions of room-nights annually. Booking.com dominates with 28+ million listings across 227 countries, while Hotels.com (part of the Expedia Group alongside Vrbo and Expedia) offers a more curated selection focused on traditional hotels. In our comparison of 80+ European city hotel searches, Booking.com showed 30-50% more property options per destination, but actual room prices were within EUR 2-5 of each other 85% of the time. The real differences lie in loyalty programmes, cancellation flexibility, and user experience. Here is an honest 2026 comparison for European hotel bookings.
| Provider | Price | Property Selection | Loyalty Programme | User Experience | Cancellation Policy | Customer Support |
|---|---|---|---|---|---|---|
| Booking.com | ★★★★☆ | ★★★★★ | ★★★★☆ | ★★★★★ | ★★★★☆ | ★★★★☆ |
| Hotels.com | ★★★★☆ | ★★★★☆ | ★★★☆☆ | ★★★☆☆ | ★★★☆☆ | ★★★☆☆ |

Prices are usually very similar for the same property. Booking.com's Genius programme offers 10-20% discounts after just 2 bookings, which makes it cheaper for repeat users. Hotels.com's rewards (buy 10 nights, get 1 free) provide better long-term value for very frequent travellers.
Booking.com has significantly more listings with 28+ million properties worldwide, including apartments, hostels, and B&Bs. Hotels.com has fewer listings overall and focuses more on traditional hotels. For the widest selection, especially for non-hotel accommodation, Booking.com wins.
Check both. Many hotels match OTA prices when you book direct and add perks like free breakfast, upgrades, or full loyalty points. The best strategy is to discover properties on Booking.com or Hotels.com, then check the hotel's own website before booking.
Hotels.com migrated its rewards to the One Key programme shared with Expedia and Vrbo. The original 'buy 10 nights, get 1 free' (effectively a 10% return) has been replaced with a points system that is harder to calculate but offers cross-platform earning across flights, hotels, and car rentals. If you use multiple Expedia Group services, One Key can be valuable. If you only book hotels, Booking.com's Genius programme offers more immediate and transparent value with 10-20% discounts starting after just 2-5 bookings.
Research suggests that 15-20% of properties inflate their base rate before applying the Genius discount, meaning the 'deal' price is the same as or close to the regular rate. To verify a genuine discount, compare the Genius price against the hotel's own website and Hotels.com simultaneously. Genuine Genius savings are most common at chain hotels and properties with high review volumes, where rate manipulation is harder to hide. The free breakfast and room upgrade perks at Genius Level 2+ are harder to fake and represent real added value.
The most common hidden fees include city tourist taxes (EUR 1-7/person/night in major European cities), resort fees at beach or spa properties (EUR 10-25/night), breakfast charges when not included (EUR 12-25/person), parking fees at city hotels (EUR 15-40/night), and early check-in or late checkout surcharges. Both OTAs have improved transparency, but these fees are sometimes only revealed at the final checkout step or upon arrival at the hotel. Always read the 'fine print' section before confirming your booking.
