I've been on a roll visiting all the high end casino spas in Vegas and Mandarin Oriental was on top of my list.
I did the day pass as I usually enjoy the facilities more then treatments so this is a review of the facilities only.
A day pass is $80
The spa is very small
They have a warm jacuzzi overlooking the strip with the metal lounge chairs underwater. The problem is that when you turn the jacuzzi the water pressure pushes you up so you really can't lay back and enjoy the view.
The area where they have the steam room, sauna and the experience showers doesn't have towels so you have to go to the first area if you need one.
One of the experience showers was broken and the one that worked was not much of an experience
Then they have a hot stone chair lounge area overlooking the strip which is not very relaxing
There was no music playing there and the one bamboo decoration was looking dried out
The tea and fruit lounge area was nice with comfy beds but I wish they had a selection of teas
Overall I was pretty disappointed and only stayed for about an 1 1/2
