I just got sent my notice for my stay tomorrow with a link to a Marriott app and it made a point of saying this was an Elite check in. Has anyone done this and is it working well (getting you a good room location)? I should be getting the lounge upgrade and a higher floor. I also particularly like being away from the elevator and stairwells.

Also, I was hoping for an early check-in instead of 4 - more like 3.
