It's 102 degrees outside and I've been awake for 16 hours, including 2 hours at airports, 5 hours on the plane and 7 hours walking through the jewelry trade show at Mandalay Bay.  I get in my room and it's STILL 102 degrees, AC's broken.\n\nCall, get re-assigned to a new room, carry my luggage across their huge resort to the lobby to get my new key and then back across the resort to my new room....AC's broken...again.\n\nI eventually got to a room with a working AC.\n\nThe rooms are really nice though.  Mine had two floors, an indoor jacuzzi, mini kitchen and a tv on each floor.
