By 1958, there were 50 locations across the country, 100 by 1959, 500 by 1964, and the 1000th Holiday Inn opened in San Antonio, Texas, in 1968. The chain dominated the motel market, leveraged its innovative Holidex reservation system, put considerable financial pressure on traditional hotels and set the standard for its competitors, like Ramada Inns, Quality Inn, Howard Johnson's, and Best Western.
