What happens: You walk into a stylish lounge filled with well-dressed men and women, eating, drinking and sighing (as the week's knots are kneaded away). Choose a 20-minute "mini" facial, pedicure, massage and more, done in a treatment room but with doors open and street clothes on. Hang out in the group room with your pals and get dual neck massages.
Price: $39 to $99, depending on the number of treatments.
Ahh factor: Now that you're relaxed and pampered, it's time for a night on the town -- or the couch and a movie.

What happens: In addition to some exotic couples treatments, such as the Kama Sutra with Shirodhara (an oil drip to the forehead), the spa also offers elaborate bath and sauna-type treatments that men and women can share, including the Laconium, a heated, round room. If that sounds too Caligula, try the Crystal Art Body Room for group applications of Swarovski crystal "tattoos."
Price: $35 for access to the bath and steam areas
