We had standard rooms booked @ Mandalay and tried the $20 sandwich trick (http://www.thetwentydollartrick.com/) and got 2 successful upgrades to THEhotel.  Gorgeous suites w/ a living room, couch, wetbar, and flat panel TVs in both rooms as well as the bathroom.  Even the hallway leading up to the elevators made me feel like such a VIP being able to stay there.
