Slip into the spa at what is arguably the world's largest hotel—the Hilton San Francisco—and make it your quiet oasis for a few hours. Facials, nail treatments, manicures and pedicures, a 200 jet hydrotherapy session, and the new microdermabrasion and Green Tea treatments for men and women are all meted out with careful meticulousness and warm attention. Those who avail of the rejuvenating baths emerge reluctantly, refreshed and ready to take on the world, while those with sore muscles have their knots kneaded away by expert hands. A well-equipped health club promises to melt that flab and build muscle. Once hooked, it's hard to break away, but the rates should keep you from going overboard!
