Just as a side note, it would be interesting to find out if the hotel oversold, and if the OP had shown up at midnight, would 6 rooms have been available. It is common practice to oversell and bank on last minute cancellations to ensure a sold out capacity. Although with the room under a platinum reservation, I doubt they would have given away the rooms, given the penalty supposedly awarded a platinum if they are walked due to overbooking. Nevertheless, I do side with the hotel on this one. Even three rooms lost revenue is a big chunk of change on a sold out date. However I thought the platinum member or the member's family had to occupy a room in order to get points for each room booked. I can understand getting points for two rooms (assuming a spouse is on the trip also) but don't they frown upon giving full points for blocks of rooms under one reservation?
