TERRIBLE!
The shower was clogged when we arrived, only to be told there were no more available rooms and an engineer would be up to unclog it.
Bathroom was also dirty. How did housekeeping forget to pick up their rags? And yes I know the difference between a towel and a rag.
Calls to the front desk were a matter of waiting on hold several minutes. This was also the case when the shower clogged again the next day.
Tram service isn't 24 hours, so please don't be fooled. If you go to see a show at any other hotel, and you leave after 1130pm (like most of the world) be prepared to walk 0.9 miles from the Excalibur to Mandalay Bay. Yes I mapped it, my feet don't appreciate walking a mile home each night. Of course you could take a cab, but, why when the tram is advertised as 24hours a day?
Also, internet access is $15 a day.
Stay somewhere CLOSER to everything else. Your feet will thank you for it.
