We are here at the Marriott Marquis, checked in on Sat. The elevator situation seems to have been solved. We have seldom had to wait more than a minute or 2. The most maybe was 5 mins. I am not sure if this is a new system, but you enter your floor number on a keypad by the elevator banks and it tells you which elevator (they have assigned letters) to wait by and when your elevator arrives, the numbers are already entered and cannot be changed. We can still see that they do not have all the elevators working and the hotel seems full, so not sure what the change is.
