Cirque Lodge, Sundance, Utah

Located on stunning Mount Timpanogos overlooking Robert Redford's Sundance resort, Cirque Lodge is fully equipped with gyms, saunas, Jacuzzis and media rooms. It captures the essence of a mountain retreat-you may even forget you're not actually on vacation. Perhaps that's why A- and B-listers like Lindsay Lohan, Eva Mendes, Mary-Kate Olsen and Kirsten Dunst have landed at its doorstep. If you don't like the après-ski feel of The Lodge—one of the center's two treatment facilities—opt instead for a stay at The Studio, a 100,000-square-foot multiplex down the road in Orem. The going rate for a room starts at $30,000 for one month.
