I've used it for the past two years and found it to be excellent for hotel stays.

Lately, I've beaten the Hotwire prices with Priceline.......but.......you really need to know the prices down cold to win with Priceline. If you put a bid too low, they reject it and you can rebid the exact same request for 72 hours. But, if you know the area and the price that they will take......it's even better than Hotwire.
