My very first stay at a Mandarin Oriental Hotel (I think!) and I was very pleased with the rooms and the location of the hotel. This is the only hotel I know of in Vegas without a casino...and it really does make a difference in the overall atmosphere. It is never difficult to find the elevators and the general feel is one of a more relaxing oasis in the middle of a very chaotic outside. It is nice to be in the chaos for a time, but when you want to rest, you can escape it all at The Mandarin. The proximity to Aria and the Crystal Shops mall is the best! Very easy to walk over and experience all the offerings over there and easily return to the Mandarin in the evening. I spent 2 days by the pool and felt that the pool staff gave the best service in the hotel. I never waited for bottled water, cocktails or food. I did order chips and salsa with guacamole that was really mediocre...surprising, I thought it would be better, guac tasted like it was previously frozen.
I stayed in a regular room with a pool/city view that was really nice - of course. I would stay here again.
