I'm not completely sure how it is decided WHICH room you get at the Marriott upon check-in. Like, is it possible to say 'Can I get a room that's as high as possible?' or vice versa? I'm assuming it's based on what is available/clean when you get there and are ready to check-in. I'm mainly asking because I'm arriving Thursday (to avoid the Friday madness!!!!) and would love to be able to have a room that's fairly close to the ground (just in case the elevators were annoying and I decided to use the stairs instead) or one that's extremely high up because, if I remember correctly, the elevator bay in the Marriott for the upper levels goes to a smaller number of levels than the other elevators bays, thus the odds for shorter elevator wait times would be increased.
