Caesars Palace was established in 1966. In 1968, Kirk Kerkorian purchased the Flamingo and hired Sahara Hotels Vice President Alex Shoofey as president. Alex Shoofey brought along 33 of Sahara's top executives. The Flamingo was used to train future employees of the International Hotel, which was under construction. Opening in 1969, the International Hotel, with 1,512 rooms, began the era of mega-resorts. The International is known as Westgate Las Vegas today. The first MGM Grand Hotel and Casino, also a Kerkorian property, opened in 1973 with 2,084 rooms. At the time, this was one of the largest hotels in the world by number of rooms. The Rossiya Hotel built in 1967 in Moscow, for instance, had 3,200 rooms; however, most of the rooms in the Rossiya Hotel were single rooms of 118 sq. ft (roughly 1/4 size of a standard room at the MGM Grand Resort). On November 21, 1980, the MGM Grand suffered the worst resort fire in the history of Las Vegas as a result of electrical problems, killing 87 people. It reopened eight months later. In 1986, Kerkorian sold the MGM Grand to Bally Manufacturing, and it was renamed Bally's.
