I only used the gym and general spa facilities...no treatments.
Fitness center is pretty good. A great vibe in there. Plenty of refreshment. The ipod-less can borrow headsets for the cardio. Good equipment and great environment. Love all those windows.
The men's spa was really really really cool. Just men lounging and relaxing. Most guys are in the buff. Lots of hot tubs of different temps and plenty of space.
Sauna is really cool...mood lights and spa music playing keeps it really relaxing and the men very relaxed. I enjoyed it. The best was the steamroom...low lights but relaxing music playing. At times, the steam pumped in really hot....but was bearable. I would say it's more relaxing than the sauna. Seems like everyone who comes here works out. You can tell by looking around. Cooled handtowels keeps one able to stay longer inside the steamroom. Seem like men just stay for hours...I sure did. Very relaxing!!! I would say the men are quite friendly there and more than willing to offer a helping hand. ;)
Amenties are excellent and showers are pretty good. The offerings of tons of beverages in little cans makes packing your gym bag with a few extras to take back to your room including bottled water worthwhile.
