A nine-story hotel addition was completed in 1964. An adjacent hotel-casino, the Royal Nevada, became part of the Stardust in 1959, with its casino converted into Stardust convention space. It had 1,065 rooms located across six motel structures, and included a 16,500 sq ft (1,530 m 2) casino. The Stardust opened on July 2, 1958, as the world's largest hotel.
Rella Factor, the wife of John Factor, bought the Stardust in January 1958, and finished construction. The Stardust had numerous creditors, and construction was stopped in 1956, when the project ran out of money. Cornero died in 1955, and the project was taken over by his brother. The Stardust was conceived by Tony Cornero, and construction began in 1954.
The Stardust Resort and Casino was a casino resort located on 60 acres (24 ha) along the Las Vegas Strip in Winchester, Nevada.
