Accommodation is usually one of the most expensive aspects of any vacation. Though booking a hotel has become easier than ever, the sheer number of platforms and offers can overwhelm most travelers. In general, the best websites feature great deals, numerous room options, and results based on your preferences. Here, we've listed top hotel booking websites that can help you get an excellent room at a reasonable price. Booking.com Booking.com has become a go-to hotel-booking website for millions of travelers worldwide. It's reliable, easy to use, and offers eclectic search results, consisting of hotels, apartments, hostels, and guesthouses. Plus, the platform provides impressive deals year-round that can help you book inexpensive accommodation in any destination around the world. Additionally, Booking.com offers excellent customer service. HotelsCombined HotelsCombined is a top-rated metasearch engine, also referred to as an aggregator. This means it compares listings from hundreds of websites, including top travel agencies and major hotel brands, and puts them in one place. The website makes it excellent for last-minute bookings. One of the highlights of HotelsCombined is that it offers a "Best Price Guarantee," which promises customers a refund of the difference if they find a hotel listed cheaper elsewhere on the web. Kayak If you've book flight tickets frequently, you might already be familiar with Kayak's interface. It's uncluttered and easy to navigate, which helps you find what you're looking for quickly. Like HotelsCombined, Kayak is a metasearch engine that collates the best hotel deals from across the Internet. It has many excellent filters, including a "nearby" tool which comes in handy when you want to find accommodation closest to a particular location. TripAdvisor Most of us have read reviews on TripAdvisor at some point, but not many people know that the website also offers hotel booking services. In fact, it's a great place to find some of the very best hotel deals in locations around the world. The website even allows you to sort your search results by best value, price, and distance to the city center. And thanks to the many reviews, you'll always know if the hotel is worth it. Agoda If you're searching for the best prices on hotels anywhere in Asia, you must check out Agoda. The platform, founded in Thailand, has been a reputed, go-to hotel-booking site across Asia. With its many filters, like star rating, facilities, payment options, and property type, it can help you find a suitable hotel in no time.  Priceline Priceline is yet another popular online travel agency. Like other websites in this list, it offers great deals on hotels throughout the year. That said, it stands out with its Express Deal offers, which help you secure a booking at an incredibly low price. The catch is that the hotel name will not be revealed until your booking is complete. It may be a good option for people on a very tight budget.
