When the park opened, there were 500 employees and 33 attractions, many of which were designed and built by Arrow Development, which designed and built many of the original attractions at Disneyland. The admission price in 1971 was $5 for adults, and $3.50 for children between the ages of 3 and 12. Because the park was in a relatively remote part of Los Angeles County, the Greyhound bus line provided bus service to and from the park and Los Angeles, as well as from Northern California, and optionally allowed purchase of park admission at the time the bus ticket was purchased.
