Walt never actually designed anything. He trusted the creative people around him to design wonderful things. It is my belief that despite it negating the original concept of Tomorrowland (a showcase of what the future will hold), the Spaceport theming of Tomorrowland '94 is something Walt would have gotten very excited about. It was a well-planned land with a great story tying all the theming together. Additionally it had fun mini-stories happening throughout, such as RoboNews. If anything, I believe he would have seen a land like TL94 fully funded so that the theming and great storytelling would have carried on throughout the entire land. Mind you, I have no way of truly knowing this. I also hate playin up the Walt nostalgia. Walt's nostalgia was mainly rooted in american history. Otherwise, he didn't exactly strike me as a nostalgic person. I believe the best way to actually honor Walt is by creating change.
