Renaissance Schaumburg Hotel & Convention Center

Soar to this eighth-floor spa in a cloud-lined elevator and melt into 9,000 square feet of premium pampering space. This New York import features 16 treatment rooms, four movie-while-you-manicure stations with personal DVD players, and a full slate of massage, nail and body treatments. Try the signature triple-layer oxygen facial ($150), said to clean, calm, hydrate and illuminate. Warning: Prices are as lofty as the lake views.
