I think this is the 2nd largest spa out of all on the strip, not compared to the Canyon Ranch @ the Palazzo. But this spa to be honest is my favorite. It's $55 for non-hotel guests on weekdays and $65 on weekends. Once you walk in to the spa, towards your right, there is the Roman Baths, which they have the hot and cold tubs. The decor is really nice, which consists of Ancient Rome. You walk down a long corridor which you get assigned your locker where you can put your personal items and get your robe from there. It is clothing optional. Once you come in, you will see the Tea Room, where they have coffee, different variety of teas, juices, etc .. and a lounge where you can watch TV. Then you have your Steam Rooms and saunas. Overall, this spa has all the amenities that you need. I like how large it is and just looking around the decor, it feels like you are in Ancient Rome. It is definitely relaxing and it is worth staying there the whole day. Get your money's worth !!
