I watched an interesting program about the hotel business (not Disney) and they were specifically asked if a guest walked in, and the room was $300 and the guest offered $200 cash, would they take it? They said no, even if it meant the room went empty. They specifically said they did not want to train their guests to think that by waiting until the last minute they could get a deal. They wanted them to book as early as possible. It was an interesting program, especially the parts about room rates (and how they fluctuate) and how hotels monitor their competitors occupancy hoping they will be the LAST hotel with availability on any given day.
