The MGM Grand Las Vegas is a hotel casino located on the Las Vegas Strip in Paradise, Nevada. The MGM Grand is the second largest hotel in the world by number of rooms and the largest hotel resort complex in the United States, ahead of The Venetian.[1] When it opened in 1993, the MGM Grand was the largest hotel 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),[2] a 380,000 sqft (35,000 m2) convention center, the MGM Grand Garden Arena, and the Grand Spa. It also houses numerous shops and night clubs, 19 restaurants, and the largest casino in Clark County, which occupies 171,500 sqft (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, the New York-New York.  
The Marina Hotel, located at 3805 Las Vegas Boulevard, opened in 1975 as a 714-room hotel and casino. In 1989, Kirk Kerkorian bought the Marina Hotel and the Tropicana Country Club to obtain the site that would become the home of the MGM Grand. During that time, the Marina was known as the MGM-Marina Hotel.

Ground was broken on October 7, 1991, for the new casino hotel complex. The Marina closed on November 30, 1990. The Marina hotel building still exists as the western end of the main hotel building.

The hotel rooms are located in several buildings including:

The main hotel building, with 5,044 rooms (4,293 rooms and 751 suites) including the SKYLOFTS at MGM Grand with 51 lofts located on the top two floors of the hotel building.

It is one of the three large hotels in Las Vegas that has a 13th floor.
