The casino accounted for half of the park at that time. In May 1979, the city council approved Sugarman to operate three blackjack tables at Westworld, and the gaming commission gave him unanimous approval for gambling operations. That month, Old Tucson Corporation announced that it had acquired many items and memorabilia from Paramount Pictures' western street that would be incorporated into Westworld's western street. Old Tucson Corporation also announced that it had purchased the rights to showcase the Elvis Presley home movies at Westworld and Old Tucson. Old Tucson Corporation was renamed Westworld Inc. during May 1979. Westworld opened in early June 1979. Priscilla Presley visited the park shortly before its opening to film an introduction to the home movies that the park planned to show in its theater. Later in June 1979, the city council approved plans for amusement rides to be built on land that was previously planned for Old Vegas buildings. At the end of the month, Alarcon was denied a gaming license as state investigators could not satisfactorily trace the source of his money, due to Mexico's different accounting procedures. In August 1979, LARC reached an agreement to assist in the management and operations of Westworld and Old Tucson. Expansions and fire In September 1979, Sugarman sold his interest in Westworld Inc. and the park reverted to its original Old Vegas name. By that point, Simmons was the overseer of gambling operations at the park. By 1980, Old Vegas included two restaurants and a casino, and there were plans to rebuild the Paramount Pictures western street adjacent to the park's Old Mormon Fort. Westworld Inc. began construction of the second phase in July 1980. The second phase would include a railroad museum and other historic exhibits, as well as the Wagon Camp picnic and barbecue areas. Part of the second phase was the Eureka Locomotive, which went on permanent display at Old Vegas, along with Virginia and Truckee Railroad equipment. Other additions would include a merry-go-round, go-karts, and an antique steam locomotive. The second phase cost $1.5 million, and was opened in October 1980. More than 10,000 people attended Old Vegas during the opening weekend of the second phase. The third phase, consisting of a western street and additional rides, was scheduled to begin construction
