Oh my goodness! Hammammmmmmm is the way to go! Wanted a real good couples body scrub followed up with a couples massage. What a great way to end my 40th birthday in Vegas. Does require a bit of $$$, but well spent while on vacation. Was specifically looking for someplace to accomodate a couple and if you've been to the Cosmopolitan, then you can have an idea of how classy this place is. My fiance and I were able to enjoy a round of rooms starting in the sauna, cold mist, then steam. A whirlpool was available for use as well. This portion of the spa is gender separated, but then you can ask to be reunited in a joint lounge prior to the hammam treatment. BTW, when we made our appointment, we were asked what our gender preference was for our massage therapist and we requested both to be women. They met us in the lounge and brought us to the hammam - a heated oval stone table where two stations were set up for our scrub and soap massage side by side. I cannot even express how relaxing this part was - getting scrubbed, massaged with water and even the way the water was poured was amazing! After our scrub, we had a brief moment in the sauna and then were led to our beautiful room for the couples massage, again side by side. Absolutely recommend to any couple looking for a relaxing spa treatment together.
