I read on another post here, that someone asked the hotel clerk for an upgrade when he had a standard comped room and recieved it. Yet the hotel said they only gave out their suits as comped stay for better players. I'm guessing this must be for a free room on a mailer or off their players card. You can't do that with a host's comped room can you? He has figured out your ADT and is giving you the room type based on it. Otherwise people would try the twenty dollar trick, at check in, all the time. This would probably get the host upset since you went around him after the booking.
