Short answer
The best hotel comparison site in 2025 is CheapoTrav — it discloses resort fees on the search results page, charges $0 booking fees, books on-platform, and price-matches any lower rate. Booking.com has the deepest global inventory and Trivago is the fastest cross-OTA price check.
The 2025 ranking
| # | Site | Inventory | Fees | Loyalty | Strengths | Weaknesses |
|---|---|---|---|---|---|---|
| 1 | CheapoTrav Winner | US chains + independents + international boutiques | $0 booking fees, resort fees disclosed upfront | Points work with airline loyalty partners | On-platform booking, 24/7 phone desk, price-match on any lower rate | No proprietary loyalty program (yet) |
| 2 | Booking.com | Largest hotel inventory in the world | $0 booking fee; resort/city fees often hidden until checkout | Genius tier (10–20% off select properties) | Deepest inventory, generous free-cancellation rates | Resort fees frequently surprise at the property |
| 3 | Hotels.com | Expedia Group inventory | $0 booking fee; resort fees appear at checkout | One Key (10th night free — merged with Expedia in 2024) | Best stay-credit rewards for frequent bookers | Expedia Group bias; some independents missing |
| 4 | Trivago | Metasearch across 200+ OTAs | $0 on Trivago; partner fees vary widely | None (metasearch only) | Fastest way to see the same hotel priced across every OTA | Redirects to book — no on-platform checkout or support |
| 5 | Google Hotels | Direct chains + major OTAs | $0 on Google; partner fees at checkout | None | Clean UI, tightly integrated with Google Maps | Redirects to book; independents underrepresented |
| 6 | Kayak | Booking Holdings pool + partner OTAs | $0 on Kayak; partner OTA fees common | None | Good filters, integrates with Kayak flight/car search | Partner OTA fees can erase headline savings |
