• Answer:

  When building Disneyland, and then Disney World, Walt made it clear that the outside world should be kept outside. From within the Magic Kingdom, no signs of the real world were to be seen. He even took pains to make sure that the workings of the park and its attractions were hidden from view. Disney World employees wear costumes or Disney garb and they are called "cast members" instead of employees. The streets are clean, the colors are bright, the sights, sounds, and smells are pleasant ones, and everyone wears a big smile, just as Walt Disney wanted it. Unfortunately, before Disney World opened to the public in 1971, Walt passed away. His brother Roy changed the name to "Walt Disney World" to honor the name of its creator.
