There are tons of great sites out there to compare hotels, flights, and even car rental prices. One site that I use and find the most helpful when searching for hotels is www.hotelseasy.net. It has similar searches to most other all encompassing search sites but seems to offer a wider range of hotels to choose from.
The site itself is very easy to use you simply plug in the dates and destination then browse the long lists of hotels to connect to for completing your booking.
I would love to hear your feedback on using this site as well as suggestions for other sites.
