Sorry if I am asking a dumb question, but I did not see this covered in looking around on this board. I am wondering how a "stay" is defined exactly. Recently I booked three rooms at a location (three separate confirmation numbers) all under my name and Marriott ID. I thought I would get "nights credit" for all three rooms but only got credit for one room. Is this the way it should have been done by Marriott, or should I have gotten three nights credit for each actual night, since I booked three rooms instead of one? Thanks to anyone who can enlighten me.
