In Brazil, Rio is party central, and in Las Vegas so is this sprawling resort just west of the Strip. The standard so-called suites don't actually have separate bedrooms, but they're spacious (at least 600 square feet), and higher-end units have double whirlpool tubs, wet bars, and other cushy touches. The overarching Mardi Gras theme of Masquerade Village has been toned down in recent years, but certain aspects remain—VooDoo Beach pool has real sand and waterfalls, and VooDoo Rooftop Nightclub is an open-air party worth checking out. New in 2014, the Rio added an attraction for thrill-seekers; a zip line that stretches from one tower to the other. Approach table games with caution—the casino edge is one of Vegas's worst. If you'd rather just watch, visit in July, when the ballrooms on the east side of the property host the annual "Main Event" of the World Series of Poker.
