Walt Disney's original concept was of a permanent family fun park minus the "negative element", which he felt traveling carnivals often attracted.
While on outings with his daughters Dianne and Sharon, Walt realized there were no parks with activities both parents and children could enjoy together.
Soon, even while they were refining and developing Disneyland, Walt and Roy began planning to expand the concept to other locations.
Parents were throwing children over the shoulders of crowds to get in line for rides such as Dumbo the Flying Elephant.
Despite the problems on the opening day, Disneyland was clearly an enormous success.
It attracted visitors worldwide in unprecedented volume.
In return, the network agreed to help finance the new park.
On the suggestion of researchers at Stanford Research Institute who correctly envisioned the area's potential growth, Disney acquired 160 acres (730,000 m²) of orange groves and walnut trees in Anaheim, south of Los Angeles in neighboring Orange County. Highway 101 (later Interstate 5) was under construction at the same time just to the north of the site; in preparation for the traffic which Disneyland was expected to bring, two more lanes were added to the freeway even before the park was finished.
Over time, Walt had received numerous letters written by people wanting to visit the Disney Studio lot and to meet their favorite Disney character.
