When I stay at a Marriott facility for a conference I can not get credit for the nights if the room is paid for my a master account. This isn't fair. I'm really not concerned about the points as I am about the nights. It would seem Marriott could cover the nights by simply getting my account number. If I charge something to my room and pay with my credit card at check out them I get points for those charges. I should get credit for those nights as well. You need to revise the program. Your competitors do give credit for nights on a master account.
