HotelsCombined.com is a unique search engine that I use to find hotel availability and rates, and to compare prices and offers from multiple merchants all at one place without having to search websites one by one to find the best deals and lowest rates. Once you find the supplier suitable for your needs, the website links you through to the supplier website to book directly.

They mention in their site that they are independent and are not paid to promote any particular website or hotel and that they are committed to showing the "complete picture" for any hotel that can be booked on the Internet today.
