We have used priceline a few times and they are very fair. Just remember, your purchase with them is BINDING and they will not refund if something comes up. We once got a hotel that only had rooms with a king bed - NO 2 doubles. I thought every 4 * hotel would have an option of 2 doubles but this one did not. It worked out okay but when I originally called priceline to express my concern, their feelings were "you bought it, too bad." It was also VERY difficult to get to someone in Customer Service. Just be aware of this.
