I planned a trip to Boston several months ago. I used Priceline. Never again. Due to a change in plans I tried to cancel the hotel room I had booked. According to the hotel, the time I booked is very busy and they could easily resell the room, but they have a contract with Priceline. Priceline will cancel the reservation, but will charge me the $200.00 for the first night. If I don't use the reservation, they will charge me for the full cost of the complete stay. If I cancel they admit they will resell the room. Usually if a room can be rebooked (ie cancelation is before the stated time), they do not charge you. I have spent a lot of time on this on the phone and on line, but they are adamant that they can do this. Seems this may be how they make money.
