If you have some time and of course money, Canyon Ranch is the place to do it. I was staying at the Venetian for a conference and was working out of my room one of those days so I thought to try Acupuncture for stress relief. I arrived at the spa and walked the very long corridor to get to the actual location and loved the plush robe, spacious locker room and facility in general. After acupuncture I had access to the spa for the day so I sat in the hot tub, the "igloo" which is a 45 degree room with trippy lights to cool off and sipped on cucumber water. The staff is very friendly and I truly felt pampered and spoiled. Loved it. I will definitely come back the next time I am in Vegas....
