The Really Cool Wife and myself always use Hotwire or Priceline. Last weekend got the King Edward for $75 a night on Priceline. If you go to Betterbidding.com, this sight gives you an idea of what hotel you will get at what price. I have used if for travel all over US and Canada. Have not paid full price for a room in quite a while, unless I had to be at a specific hotel and could not risk getting another. Both services, Priceline and Hotwire guarantee the neighborhood and quality of the hotel, not the specific hotel until you actually commit to the purchase. Betterbidding helps you know ahead what hotel it will be, but while it has always been right for me there is no guarantee.
