Delano Las Vegas at Mandalay Bay

There were signs of a truce between the Vegas casinos and the coastal boutique hotels, but with the Delano Las Vegas at Mandalay Bay we have decisively entered an era of full collaboration. This tower’s thousand-plus suites range from very large to positively vast, and their white-and-neutral palette and Art Deco inspiration make them among the most stylish in town. Its several restaurants include one by Alain Ducasse, its nightlife options include the panoramic Skyfall Lounge as well as a big-deal nightclub, there’s a Beach Club (actually a pool) and a swanky full-service spa, and the Mandalay Bay’s live entertainment venues — think Michael Jackson ONE by Cirque du Soleil — are close at hand.
