This just in. Starwood's sexy brand of W Hotels is giving away a third night free when you book two nights. Embrace the cutting-edge and cool at W Hotels across the country and around the world (and now in Doha, to boot). You'll dig the hip Living Room Lounges-- the W Wonderland-- and Whatever/Whenever service (translation: your wish is their command). Some of our fave W properties include the W New York Union Square, the W San Francisco, and the W in Seoul.
