On my second trip to Las Vegas with Carole C., we went here for a spa day of sorts. I haven't been have other treatments in other Vegas spas, but the ambiance was amazing. Highlights are the salt room (you can go in here and breathe the salt in, air feels lighter and fresher while in big comfy chairs and listening to ambient sounds through noise canceling headphones...), the jacuzzis and the seperate pool for spa guests. This one is heated, which is nice.
We had a full on spa day here, and it was well worth the money. Massages (my masseuse was kneading my back so wonderfully I didn't even notice that she'd climbed on the table with me to get better leverage), body scrubs, etc...make for two happy ladies!
