After scouring several popular discount sites for a month prior to departure, I came upon this website/app and Im so glad I did! I received a much better deal than blindly bidding on rooms through Priceline or Hotwire and their taxes and fees were much lower than those mentioned above. I was able to use their HT Ace to make room requests after booking.
Really great, well thought out App. I will use again!!!!!
