Saving Tomorrowland is probably the hardest job, simply because nobody knows what Tomorrow looks like. Therefore it is the job of dreams. But these days, it seems to me, many dream about what was or what never will be (fantasy) as opposed to what is.
But for fun, let's imagine the future:
First and foremost, we discover cold fusion. The dream of neverending energy is real (likely, no, this is a dream). However, suppose a corporation wants to steal the formula to keep charging tons of money for fossil fuels? Could a ride really be based on rescuing a fusion formula, driving through a winding chase down the freeway in our futuristic car while helicopters fly over us, we dodge traffic and other cars try to knock us of the track. While driving we're frantically trying to upload the formula to the internet, and occasionally we lose the signal when forced into a tunnel. I picture something like a long "Test Track" designed to look like a Freeway at night, passing futuristc buildings along the way and weaving in and out of traffic. At the end, the formula is on the internet, the cops show up just in time to nab the bad guys, and the future of energy is secured. The giant show building is made to look like a skyline, think New York, New York in Vegas with futuristic buildings, where Autopia is.
Second, we have built an underwater city. We are visiting said city when it's attacked by a sea monster. We walk through as power fails, tank walls collapse, leaks rise and water threatens us all. We then have to board an escape sub and get to the surface, dodging this mighty beast and floating debris. I picture a walk-through first half, followed by a motion simulator. Picture this where Buzz is.
Third, rather than streets we have canals as the major thoroughfares in some cities. People park outside cities themselves then take a small hovercraft (aquatopia) from the parking area into the downtown. There is less crime, robberies, pollution (these are electric boats) and concrete baking the city and more cool waterways, etc. I picture building a city on the lagoon (bye bye Nemo) while we aquatopia our way through the canal system.
Fourth, travel to the stars is within the layman's reach. We get to pilot space shuttles. Astro Oribitor and Space Mountain remain (Astro moved up top again), but are changed to fit a new theme. Think like Macs and Ipods., sleek whites and aerodynamic designs. Minimalist looks on everything.
Fifth, mass transit in general has improved. The resdesigned people mover is back, along with an enclosed skyway. The bright colors are again more like the blacks, silvers, whites and metallic look gives them a feel of fast. The skyway has a fine but strong mesh netting and heavier care to discourage throwing things or shaking the cars.
We walk through a space station on Mars. Nothing in particular happens, we just enjoy thrilling vistas, a Sand storm, and view robots doing research. This space fills up Starcade and HISTA (via an escalator) with fake windows on the world.
Innoventions is a fine idea, they just update it more often and people can see a not-far-off tomorrow.
Finally, Star Tours opens up flights to Naboo and Coruscant as well as Endor. Like an airport, you must find your terminal and wait to board. Allows people to enjoy Endor without a long wait, while people reride to try the other two destinations.
