The Mirage spa is really nice. First time I came here was because the hotel messed up my room and made us wait so they comped us two days at the spa. After that I have been an avid customer of the Mirage spa. Even if I stay some where else I always make it a point to stop here. The best part is the steam room with the dark lighting and relaxing music.
It's so pleasant there that one time I fell asleep because the steam room relaxed me so much. The gym is also another element of the spa that is sublime, not very busy and most of the time there are only about one to three people. They even provide you fruit, water, nuts and coffee so you may snack or even have a semihealthy-lunch or breakfast.
