Book it thru the Club, call the host and tell him why you are doing that. I would imagine that if your play warrants it, he will comp the room or give you a casino rate at the end of the stay. I would imagine the Club gets credit for the booking, the casino gets your action and you get a discounted room or even free.

Most hosts want to make you happy and they have the ability to take care of situations like this. Give him a call and I bet he'll help you work it out.
