I recently visited Mandalay Bay for the first time, as an attendee of a large conference.
The rooms are large, spacious, and clean. The room was always carefully cleaned whenever the hotel staff came in. My room included a full bath, which was also really nice!
Mandalay has a huge selection of restaurants and bars that are busy at all hours of the night, with good drink specials and decent food prices.
I'd also say that the hotel is very family friendly, if pool time is of interest to you; it's probably the most popular feature here as far as entertainment goes.
The convention center is spacious, and well-run. It can be a bit of a maze, but it serves this purpose well!
