Super hotelier Steve Wynn brings intimacy to opulence with this hotel-within-a-hotel concept, thanks to koi fish ponds and a live pianist in the bar. Roger Thomas’ hyperstylized design touches, like the mosaic butterfly floors in the hotel’s private entrance. For the full Vegas effect, book a patio table at Parasol Down overlooking the Lake of Dreams. There’s a free show every 30 minutes that includes light projections on a wall of water. Indoor access to the Wynn and Encore complex means you never have to leave the premises (casinos, restaurants, high-end shops, spas, an exclusive country club and even a gawk-worthy Ferrari dealership).
