There are plenty of threads regarding how to fix Epcot (realistically) or DHS (realistically) or other global parks like Disneyland Paris...
Okay, I'm going to put up a thread about this idea in more detail later on (an extension of another thread: http://forums.wdwmagic.com/threads/a-goofy-themed-dark-ride-with-no-place-for-it-to-go.856525/), but for right now, I have an idea about something that I don't think would fit in Epcot or the Studios or even Disneyland Paris. It will be part of a land I'm working on. It's based on an abandoned concept: "Goofy About Road Trips". Here's a concept art piece:

The description reads thus:
The basic ride concept for this would be loosely based on "A Goofy Movie" and be about a cross-country road trip by the anthropomorphic friend of Mickey's. The attraction took riders on a journey with the absentminded Goofy where things went awry and mayhem ensued.
Now, certainly, this would never fit in Epcot, even if it were tacked on to, say, Test Track, which seems just forced to me. And at the Studios, I'd be picturing it as a working movie set concept and making the road trip just a movie, and thus it would be a cop-out. It would only be adding to the fact that the Studios park is so messy right now. As for Disneyland Paris, it might work in a Toontown concept (at Disneyland Paris, not at the Studios park), but I don't know if the French are as real big on road trips as Americans are.
Anyway, I'll put up this idea of mine later on in another thread.
