Been to this hotel a couple of times and it is just ok. Nothing really stands out except for the fact that it is close to the Mandalay Bay and THEHotel which is where I needed to be.
I've stayed at the East Tower (the newer building) and it is a pain to get there by walking through maze-like corridors before getting to the elevators.
Casino floor is disjointed, bars are ok, exhibitions (Bodies and Titanic) feel as old as the pieces they are showing.
What was surprising was that the rooms were not priced cheaper than the Mandalay. Guess it must really be popular because of location? I have no issues staying here again, but would not seek it out either.
