THEhotel at Mandalay Bay

Fashionably minimalist, THEhotel is meant to feel like a boutique hotel (though with 1,117 rooms, this is hardly the case). A non-gaming property, it adjoins Mandalay Bay but has its own lobby and check-in, full-service spa (The Bathhouse), and high-profile lounge (Mix in Las Vegas) on the top floor. Rooms, in mellow grays and tans, average a generous 725 square feet and have spacious marble-and-granite master baths with separate powder rooms, giant 42-inch plasma TV’s, and floor-to-ceiling windows. Despite the Mandalay Bay’s location right next door, THEhotel is still removed from the fray, with a contemporary art-filled lobby that always feels exclusive and clubby.
