It is also the third-largest hotel complex in the world by number of rooms and second-largest hotel resort complex in the United States behind the combined The Venetian and The Palazzo. When it opened in 1993, the MGM Grand was the largest hotel complex in the world.
Owned and operated by MGM Resorts International, the 30-floor main building is 293 ft (89 m) high. The property includes five outdoor pools, rivers, and waterfalls that cover 6.6 acres (2.7 ha), a 380,000 sq ft (35,000 m2) convention center, the MGM Grand Garden Arena, and the Grand Spa. It also houses numerous shops, night clubs, restaurants and the largest casino in Clark County, which occupies 171,500 sq ft (15,930 m2).
Located on the Tropicana - Las Vegas Boulevard intersection, pedestrians are not allowed to cross at street level. Instead, the MGM Grand is linked by overhead pedestrian bridges to its neighboring casinos: to the south across Tropicana Avenue, the Tropicana, and to the west across the Strip, New York-New York.
