I've used priceline with mostly lots of good experiences. The one problem I had was in Flagstaff AZ at the Holiday Inn. They put me in a single, smoking room. Even though PL says you will get NS, queen bed, it is really up to the hotel in the end. I would have moved and eaten the cost if they hadn't moved me first thing in the morning when a room opened up. It was really gross. I booked the room really early and called to confirm my late check in so I wasn't the last one to get a room... just the only one paying below the regular price... which they made a point of mentioning several times.
