Two massage therapists indeed prove twice as effective. In the Alpharetta spa's largest treatment room, a duo of practitioners work in tandem: They begin by unknotting the back with fluid, simultaneous motions, then one kneads the shoulders while the other works on the legs. The experience disorients in the most relaxing way possible. The massage is $170 for sixty minutes; $250 for ninety. Achieve an even deeper sense of calm by adding shirodhara, an Indian Ayurvedic treatment in which warm, herbed oil is drizzled over the forehead and then massaged into the scalp. It's $65 for an additional thirty minutes, and you'll want a nap afterward.
