My favourite hotel in Las Vegas. It has it's own dedicated entrance so you don't have to go through a casino to get in and out but it is part of the Mandalay Bay complex so you still can access that casino quite easily.
Mandalay Bay has also the best pool complex and clients of "The Hotel" have full access to it. This was a big point for my wife and son when they came here with me while I was at a convention (three years in a row).
Rooms are quite large (most are suites) and the decor is nice and understated. Service is top notch.
The unknown part is that it's been rebranded this year to "Delano Las Vegas" so I don't know how it will affect the place and the price.
