How big a budget do I have to work with? Assuming unlimited for the sake of conversation, and assuming I can't immediately halt the Guardians project, here is what I would do:
- Revamp Spaceship Earth's descent in a way that underlines - and completes - the spirit of the attraction.
- Gut Imagination and return the attraction to E-ticket status in a way that honors the first version of the ride, but does so with state of the art tech. A ride about imagination should make the guests' jaws drop and show them truly unbelievable things. I'd take a page from the way Mystic Manor blends real sets, AAs/animated figures, and projection mapping. It should be visually dazzling. If other characters must be involved in some way, so be it, but it would remain Figment-focused.
- Gut the Innoventions buildings and turn them into proper expo space for tech companies to show off experimental and prototype ideas. If there are no serious takers, consider turning one side into a small dark ride of some kind, subject TBD (health? weather? energy?).
- Demolish Wonders of Life and build "New Horizons," meant to be the new "thesis statement" ride of the park. Take the "If we can dream it, we can do it" ethos deep into the 21st century and depict what the most current, cutting-edge thinking about the original ride's concepts are today.
- Beautify walkways and other guest areas; more foliage, trees, and water features. Perhaps more color, so there's less of a grey feeling around that half of the park.
