The following is from a hotel perspective:
From a hotel room perspective, I believe the rooms at Mandalay Bay to be some of the better ones. I appreciate that the establishment itself is in the mix of things and places that I want to see; so that is a plus. In addition they have pretty good food options on location; such as RM Seafood, the House of Blues and some lighter fare. They are also connected to a pretty decent shopping area.
Okay, back to the rooms. The bed is comfortable and the shower/bathroom is very inviting. The room was quite clean and did not smell. In addition the space itself was fairly large for a Vegas hotel room.
