The Chocolate Box, Las Vegas

Outside, fountains pulse, bright lights shine, and sidewalks remain crowded well into the night. But inside the Spa and Salon at the Golden Nugget, classical decor and full-body spa services keep the outside world at bay. BestOfVegas.com says, "evokes class, elegance, and luxury." Within the spa, aestheticians perform massages or body treatments with organic royal honey or seaweed that go hand-in-hand with salon services to craft a knockout nighttime look. Beyond the beautifying treatment rooms, clients can jog, run, or endlessly summersault on Cybex cardiovascular machines poised above the hotel's shark tank.
