Even with just waxing services, I had access to the spa! The access is for use of the Jacuzzi, sauna and lounge areas for relaxation. You'll also get some complimentary coffee, tea, water and fruit. It's not a lot, but it is a nice place to go and escape the craziness of the strip and Vegas in general.
The waxing services was great! They are very gentle and do a good job of preventing irritation and redness. It was pricey, but that's what you get for going to a spa on the strip for just simple waxing. It's very convenient if you are staying at the Mandalay.
Remember...you are paying for Ambiance! You get what you pay for at this spa. This is one of the nicest spas I have ever been to. The decor, the quietness and the zen feeling is amazing here.
I would gladly come back for a round of pampering....when I have cash to spare.
