It depends on the hotel and the dates. No single site is always cheapest. Prices for the same room can differ between Booking.com, Expedia, Hotels.com and Agoda, which is why it is worth comparing before you book.

With the provider. You choose an offer here and book on the provider's own website. The booking, payment, changes and refunds are handled by that company.

No. You pay the provider's normal price. Some links are affiliate links, so we may earn a small commission at no extra cost to you.

Usually, until a deadline. Free-cancellation rates can be cancelled without charge until a set date, often one or two days before arrival. After that, a fee or the full stay may be charged, so check the terms on the booking page.

Taxes and fees. Some sites show the nightly rate without taxes, city tax or service fees. Always compare the total price on the final page, for the whole stay.

Early for busy dates. For high season, holidays and events, booking early gives more choice. Outside those dates you can often find good last-minute rates, and a refundable booking lets you switch if the price drops.
