So like, in the United States, if you book directly via Marriott, the number of beds isn't guaranteed unless you have some reasonable status at the hotel.

If you book a queen room isn't it always 2 beds? A king room is usually 1 bed. Is there some option where it's just totally random what room you get? I don't have any Marriott status but going on their site I can clearly see a choice of rooms, and each one says what amenities it has.
