DISNEYLAND is the only theme park that was fully designed and enjoyed by Walt Disney. He absolutely loved the place, often spending the night in his private apartment over the Main Street fire station. Cast members soon learned his habits. For example, if he was dressed up in a professional suit, he was most likely in the park on business. Perhaps he was hosting a potential sponsor or was planning out future attractions.
When he was "dressed down", however, he was most likely there for pleasure or perhaps just to dream. Much of the time he got great joy in watching the guests enjoy his Magic Kingdom.
No matter what he was doing in the park, however, he always found time to greet his beloved guests.
