This modern, health-minded spa from Arizona focuses on well-being. Offering more than 100 spa and salon services and fitness activities, it specializes in massage and couples' side-by-side therapies. On the spa's hydrotherapy circuit, you can move lazily from a herbal laconium to the salt grotto to a meditative wave room. The spa cafe serves light cuisine and fresh fruit smoothies.

To get here, take the private elevator next to the spa's Living Essentials boutique inside the Grand Canal Shoppes at the Venetian.
