My family got treatments here this weekend and it was a lovely spa. The check in staff was nice enough but we were informed upon checking in that tips were already included on our bills and we couldn't remove them. This kind of turned us off and we inquired about canceling our appointments... they have a 2 day cancellation policy which I think is excessive. So basically we were forced to tip our technicians the amount that MGM wanted them to be tipped, which I didn't think was all that awesome.
The spa is split into a men's and women's spa but all of the treatment rooms are shared - private, but shared between the two spas. They're well appointed with steam rooms and a large jacuzzi for each one. My dad got a deep tissue and said it was absolutely fantastic. My sister and I got manicures that were good but not worth the $160. We got them on Saturday and it's Tuesday and my polish has almost entirely chipped off! My tech used Seche Vite for the top coat so I know it wasn't that, but she had the balls to dilute the polish she was using on my nails with acetone in front of me... something that makes polish chip. For $160 mani/pedis I thought that was a really crummy way to handle your materials. My technician was sweet though and the actual manicure and pedicure were good. Just bring your own polish and know it's going to be overpriced. Overall I've had better for the steep price but I'd probably go back.
