Which hotel booking site is actually cheapest?
Booking.com, Expedia, Hotels.com, Agoda, Kayak and Vrbo compared on what changes the final number — fees, cancellation terms and who owns the inventory. Plus a five-minute method to check for your own dates.
The short answer
There is no site that is always cheapest, and anyone telling you otherwise is selling something. The same room is often listed at the same headline rate across every major site, because most hotels enforce rate parity in their contracts. What actually differs is the total: resort fees, taxes, currency conversion, whether you prepay, and what a member login unlocks.
So the useful question is not "which site is cheapest" but "which site is cheapest for this trip". That depends on three things: where you are going, how long you are staying, and how many people are coming.
- Hotel, anywhere, one to three nights: Booking.com or Hotels.com
- Hotel plus flight together: Expedia
- Anywhere in Asia: Agoda, almost always
- A house, a condo, or four people or more: Vrbo
- You want to sweep everything at once: Kayak
- You care more about reviews than price: TripAdvisor
Same room, same night, different total. The gap is almost never in the headline rate — it is in the fees underneath.

Site by site, and what each one is best at
Booking.com — the widest hotel inventory
Best all-rounderWins when: you want a hotel, you want to pay at the property, and you want to be able to cancel.
- The largest hotel and guesthouse inventory of any single site, including small independents the others skip
- Free cancellation on a large share of listings, and "book now, pay at the property" on many
- Genius member discounts apply after a few stays and are worth logging in for
Watch out for: non-refundable rates shown alongside flexible ones — the cheapest line on the page is often the one you cannot cancel.
Check rates on Booking.com →Expedia — best when the flight is part of it
PackagesWins when: you are booking flight and hotel for the same trip.
- Package pricing can undercut booking the two separately, sometimes substantially
- One Key rewards carry across Expedia, Hotels.com and Vrbo, which share an owner
- Strong US hotel coverage and a solid app for changes on the road
Watch out for: package fares are frequently harder to change than the two bookings separately. Read the change policy before you save fifty dollars.
Check rates on Expedia →Hotels.com — best for frequent hotel stays
LoyaltyWins when: you stay in hotels often enough for rewards to matter.
- Hotel-only focus, so the search is simpler than the all-in-one sites
- Rewards nights accumulate across stays and stack with One Key
- Inventory overlaps heavily with Expedia, so it is worth checking both — the member price is not always identical
Watch out for: the advertised price and the member price can differ by a lot. Always compare while logged in.
Check rates on Hotels.com →Agoda — the one to use in Asia
Asia-PacificWins when: you are travelling anywhere in Asia or the Pacific.
- Deepest inventory in Southeast and East Asia, including properties the Western sites never list
- Frequently prices below the others in the region, sometimes by a wide margin
- Local-market promotions that do not appear elsewhere
Watch out for: prices may display excluding tax by default, and currency conversion can add a few percent. Switch the display to include taxes and fees before you compare.
Check rates on Agoda →Vrbo — best for groups and longer stays
HomesWins when: there are four or more of you, or you are staying four nights or more.
- Whole homes and condos only — no shared rooms, which suits families
- A kitchen and a laundry change the real cost of a week away more than the nightly rate does
- No resort fees, which is a meaningful saving in cities like Las Vegas
Watch out for: cleaning fees and service fees are charged once, so they punish short stays and barely register on long ones. Compare the total, never the nightly rate.
Check homes on Vrbo →Kayak — best for the first sweep
MetasearchWins when: you want to see everything at once before deciding where to book.
- Searches the booking sites simultaneously rather than holding its own inventory
- Fast way to spot when one site is genuinely out of line with the rest
- Useful filters for price, rating and neighbourhood in one pass
Watch out for: it hands you off to whichever site holds the booking, so cancellation and support are that site's, not Kayak's.
Search on Kayak →TripAdvisor — best when the reviews decide it
ReviewsWins when: two hotels are the same price and you need to know which one is actually good.
- The deepest review archive of any travel site, going back years per property
- Compares live rates across booking sites for the property you are reading about
- Photos from guests rather than the hotel's own photographer
Watch out for: reviews skew toward the extremes. Read the three-star ones — they are usually the most accurate.

| Site | Type | Strongest at | Pay later? | Best for |
|---|---|---|---|---|
| Booking.com | Hotels, guesthouses | Inventory breadth | Often | Most hotel trips |
| Expedia | Hotels, flights, packages | Bundles | Sometimes | Flight plus hotel |
| Hotels.com | Hotels | Loyalty rewards | Sometimes | Frequent stays |
| Agoda | Hotels, apartments | Asia-Pacific pricing | Sometimes | Asia trips |
| Vrbo | Whole homes | Space per dollar | Rarely | Groups, long stays |
| Kayak | Metasearch | Seeing everything | Depends | The first sweep |
| TripAdvisor | Reviews, metasearch | Review depth | Depends | Choosing between two |
Policies vary by property as much as by site. Everything above describes what each platform is generally strongest at — the individual listing's own terms always override it.
How to find the cheapest in five minutes
This is the sequence we use. It takes about five minutes and it works for any destination.
- Start on a metasearch. Run your dates through Kayak first to see the whole field and identify two or three properties worth pursuing.
- Open those properties on two booking sites. Booking.com and one of Expedia or Hotels.com. Log in on both — member pricing is frequently the entire difference.
- Compare the total at the final screen, not the search results. Taxes, resort fees and cleaning fees appear at different stages on different sites. The search page number is not the price.
- Check the cancellation terms side by side. A rate twenty dollars higher that you can cancel is usually worth more than the twenty dollars, especially months ahead.
- If there are four of you or it is four nights or more, price the same trip on Vrbo. Divide the total by nights and by people before you compare — that is the only fair comparison against a hotel.
- Book the refundable option now, and check again a week before. Rates move. A free cancellation means you keep the upside without carrying the risk.
Four traps that make the cheap rate expensive
Resort fees
A mandatory nightly charge, collected by the property at check-in, excluded from most headline rates. Common in Las Vegas, Orlando and much of Mexico, and running $30 to $60 a night. Two hotels twenty dollars apart on the search page can end up level once the fee lands.
Prepaid versus pay-at-property
The cheapest line is almost always the prepaid, non-refundable one. That is fine if your dates are locked. If they are not, you are buying a discount with a risk you may not want to hold.
Currency conversion
Booking in a currency other than the property's can add two to four percent through the site's conversion, on top of whatever your card charges. Where possible, set the site to the local currency and let your card do the conversion.
Cleaning and service fees on rentals
Charged once per stay rather than per night. A rental that looks expensive over two nights can be the cheapest option over seven. Always divide by the number of nights before you judge it.
Common questions
Is it cheaper to book direct with the hotel?
Sometimes, and it is always worth the thirty seconds it takes to check. Hotels increasingly offer a member rate that undercuts the booking sites, or throw in parking or breakfast to win the direct booking. What you give up is the ability to compare, and often the flexible cancellation terms the booking sites negotiate.
Why is the same room the same price everywhere?
Because most hotel contracts include rate parity clauses that prevent a site from publicly undercutting the others. That is exactly why member logins, package bundles and loyalty rewards exist — they are the legal ways around parity, and they are where the real differences hide.
Do prices drop closer to the date?
Sometimes, and sometimes they climb steeply. It depends on how full the property is and what else is happening in the city that week. The reliable approach is to hold a refundable booking and check again a week out, rather than trying to predict the curve.
Does clearing cookies or browsing privately get cheaper rates?
It is a persistent myth with very little behind it. Rate changes between sessions are almost always inventory and demand moving, not the site recognising you. Logging in usually helps far more than hiding, because member pricing is real.
Which site has the best cancellation terms?
Booking.com generally makes flexible rates easiest to find and filter for. But cancellation is set per listing, not per site — the same hotel can be flexible on one platform and non-refundable on another for the identical room.
Is Agoda really cheaper in Asia?
Frequently, yes. It holds inventory and local promotions that the Western platforms do not, particularly in Southeast Asia. Just make sure the display is set to include taxes and fees before you compare it against anything else.
Now pick the right area
Choosing the booking site saves you a few dollars. Choosing the wrong neighbourhood costs you an hour a day. These guides go area by area, with measured walking distances and observed rates.
