Came here on a Sunday afternoon in July. It wasn't crowded at all. I saw only about 5 other women wandering and relaxing here and there. When you arrive you are greeted by very friendly women and they show you around. The plush robes and slipper shoes are comfortable and you get a nice sized locker for your clothing. Its clothing optional in the spa area, and it felt very clean.
I was very happy with my experience, but the price of the massage left me wanting more. In the end with tip a 60 min massage was $175, but includes use of the facilities for the day. Next time I think I would opt for the day pass, without a treatment, and use the hot tub, wet and dry saunas and nice shower area. One of my favorite things was the vanity area for after the spa. They had toothbrushes, combs, tons of hair products, and hot hair tools. Pretty much anything you need to get ready.
The massage itself was good. I liked the use of hot towels(?) throughout it and the room was nice and dark which was relaxing.
This is the perfect spot to end your Vegas vacation, just expect to spend all of your casino winnings!
