The Mandalay Bay was such a nice hotel. My husband and I had gotten an upgrade after our reservations were all messed up. They were very accommodating and super nice. My only issue was that I had reported someone spilling red wine in one of the elevators and that it could've been a safety issue. Hours later it was still there. That was a little disturbing. Besides that everything was great. The staff was friendly, the hotels were clean, and the pools were nice. Although we didn't swim because it was too cold for us. :) The hotel itself was very calm compared to all the others. Not too many youngins running around so good if you have little ones staying with you. Stay at this hotel. You will not regret it.
