In a word: SWEET. As with any spa, there's essentially a guy's side, a girl's side and a co-ed section. Since I can't comment on the girl's side, I won't. ;)
As for the guy's side, how great of a place is this? Visually stunning. A lounge area complete with two flatscreens, steam room, treatment room, locker room, etc. And then an indoor/outdoor hottub area that also boasts lounge chairs and another flatscreen!
Brilliantly conceived and it's all included in the Green Valley's resort fee, so no need to pay anything additional.
The gym has everything you would expect or need, there's a separate dance studio area and a private pool area outdoors where you can also enjoy drinks/dining.
Blessings to Heather, the pool-side server, who made sure my salad came out extra pronto because I had to get back to The Strip for an afternoon convention session.
I highly recommend the Spa at Green Valley Ranch Resort.
Trust me; I'm an Elite. ;)
