Las Vegas
Qua Baths & Spa

One of the latest spas to open in Sin City, this water-themed spot differs from its other Strip counterparts through unusual offerings like Sleep Health; the massage followed by a hypnotherapy session is a welcome relief in a city known for encouraging late nights. Caesar’s Palace, 3570 Las Vegas Blvd. S.; 866/782-0655; quabathsandspa.com; $280.

Los Angeles
InterContinental Century City

Forget standard treatment rooms. Services at Los Angeles’s InterContinental are performed in private villas with flat-screen TV’s and meditation gardens. During the Mediterranean Olive Scrub Massage—an exfoliation with crushed olive seeds and an olive-oil massage—guests are given time in the room’s infinity-edge Kohler tub, making it easy to soak it all in. 2151 Ave. of the Stars; 310/552-0425; ichotelsgroup.com; $190.

Seattle
Ummelina International Day Spa

Most treatments at downtown’s Ummelina begin with a foot soak and tea ceremony. Seaweed Pedicures are performed in private rooms where you are literally tucked into a plush heated bed. You’ll doze off while your toes are filed, buffed, and polished. 1525 Fourth Ave.; 206/624-1370; ummelina.com; $80.
