Hotel booking web site

I am sure I have seen a recmmnedation for a web site to get good rates on Las Vegas hotels but cannot find it at the moment.

Any recommendations anyone?

Thanks

http://www.travelaxe.com it is a program you install on your hard drive. Have a look on there and then go direct to the hotels own website, almost always you will pay less, and you only usually have to pay 1 nights deposit, and can cancel within 24 hours of arrival if the price goes down
