Hotels are long steeped in Las Vegas legend. The Bellagio, the Cosmopolitan, and the Encore at Wynn are some of today's biggest, and most over-the-top hotels on the Strip. For something more intimate in the center of the action, book the boutique Cromwell hotel. The Palazzo—the kid sister to the iconic Venetian—is known for its spacious suites with sunken living rooms and being home to a Canyon Ranch SpaClub. It's hard not to get lucky when you stay at one of these glitzy Las Vegas hotels.
