The Las vegas Adviser has been touting Travel Axe as a great web site search engine for Las vegas acomadations. So I've been playing around with it a bit.
One word of caution though....Yesterday I punched in my dates (2 nights) an unusual low price came up for the Hyatt Las vegas. Upon closer inspection the reason for the low price was one of the nights where not available, but it still gave me the one nite price without any kind of warning telling me either the place wasn't available for both nights or that it was only a one of my nite quote. You can figure this out yourself if you know what your looking for, like I did. However since this is a new tool, it may be easy to be fooled your getting a super rate, when actually, your only making a reservation for 1 nite.
To use TravelAxe, you must download a program on to your computer. It takes quite a bit of time to search all the travel sites, so this is by no means a quick search.
I intend to go back to the site sevearl more times, and see as my dates get closer how the site works for those dates.
