For instance, some early ideas for Florida were done only recently. The idea of a little village was there from the beginning and now we have this "Celebration" village. Same thing for the Disney Institute. Walt talked about this idea in the very first.
Walt's idea was that - as soon as the people who were dining got through their main course. They were supposed to all be seated, served at the same time, when they got into the dessert.
Well, it was never supposed to be like that. Walt died before we had finished. The original idea of Walt's was that you came down there, into the caves, and there were no pirates. But they had been there just seconds before! There was a hot meal on the table, steaming.
We finally found out the technique of separating and getting information about where every train would be at any moment. Of course, I went over budget many times, because - as you go along - some things improved, and you get better ideas.
Walt understood all of those things, and even common things about people. For instance: Usually you get your idea of what kind of day it is by looking at the horizon, because the horizon is your eye level. So what Walt did is to eliminate the horizon.
