No smoking. No gaming. No one lugging around yard-long margaritas. The Mandarin Oriental feels like an oasis amid the Strip’s chaos and clamor, with 392 guestrooms and suites ranging from 500-3,100 square feet. The decor is appropriately minimalist without feeling austere and floor-to-ceiling windows offer panoramic views of the Strip and the surrounding mountains. Be sure to grab a cocktail at the alluring Mandarin Bar on the 23rd floor before retreating to your tub for a serene soak while watching Las Vegas’ nightly light show.
