I was fascinated by the original plans for EPCOT, because I was fascinated by all things futuristic as a small child. I was unfamiliar with the level of micro-managing assholery that was also part of the plan. At some level, since Celebration is an actual planned residential community created by the Walt Disney corporation, it, not EPCOT(as built) is the true child of EPCOT(Walt’s dream) Without the futuristic transportation or completely enclosed city center, it does have a modern variation of the corporation as local government as envisioned by Walt in the form of a HOA. The architecture is completely unremarkable, the same as many other planned communities. Sadly, the idea of some private company telling you what color your drapes must be is also completely unremarkable these days. It’s like paying a mortgage to get the privilege of being a tenant.
Edited to add: I remember the model when it was part of the carousel of progress in Disneyland… https://sites.google.com/site/theoriginalepcot/
