The Mayflower calls its new spa a "mind-body experience." What they should call it is an out-of-body experience. The ethereal 20,000-square-foot retreat is impressive by any standards and has service to match (personal spa advisor, anyone?). An almost overwhelming assortment of active options--yoga, tai chi, cardio-karate, mountain biking, fly-fishing, tennis--pales in comparison to the spa menu, which includes facials (try the signature Mayflower Harmony), heavenly massages and exclusive body treatments like the Wild Lime Shiatsu Fusion. Spa weekends don?t come cheap, but we guarantee your body (and mind) will thank you.
