A friend and I will be staying at a Hilton in a couple of weeks for 2 nights. Does any one have experience whereby I register for the first night and pay the bill the next morning and then my friend register with his own credit card for the second night. We each have honors membership and are registered in the 50,000 pt. promo. 1) will this be a way in which we can each get credit for 1 night? 2)would we have to vacate the room after the first night and change to a new room for the second night? Any help/suggestions would be appreciated.
