Going to stay 2 nights (weekday) by the middle of May. Toss-up between Aria (M-Life) and Cosmo (badass hotel). Just looking for a basic King nonsmoking in a relatively quiet area with a nice bed; someplace I can retreat to either relish in my winnings or lick my wounds. I've seen Aria room videos and also heard the Cosmo basic room is 2 queens. Never saw the use in an extra bed taking up space, unless it's a kickass bed (a la Mirage). In one Aria video, it was advised to get a room on at least the 25th floor. Any other suggestions?
