I mean...just off the top of my head... LOL
1. Living Seas: Mariana Trench Exploration submarine simulator.
2. The Land: Good as is...update Living with the Land
3. Journey Into Imagination: Take the original attraction and add today's tech with new effects and better animatronics. Bring the playful Figment back. Remove the theater and create a new Table-Service restaurant where you can design your own meals and color your own little "booth/pod". If you want to eat under the sea, go ahead...if you'd rather eat on the desert...be our guest...how about space? (See what I did there?)
4. Spaceship Earth: Keep the theme...just update the scenes to make it thrilling (not thrilling in the sense that your ride vehicles fly down a coaster track or get launched). Have the scenes tell the same story but interact with the ride vehicles. Rather than driving by the scenes...make it seem as if you're a part of the scenes.
5. Guardians is a done deal.
6. Wonders of Life: Inside Out as your IP. Have a simulator attraction based around the "Train of Thought" and along the ride different scenes and effects evoke your feelings... Joy could try and combat all of the other feelings and at the end, come together and show that all the feelings need to work together to get through a day. Have a Sunshine Seasons type of Food Court in it. Each section devoted to the emotions. The Disgust area could be pretty daring. Fear could have "monster" themed items... Joy could be desserts...
7. Mission:Space: Revamp the ride itself. The restaurant is a step in the right direction and screams "opening day Epcot" to me.
8. Test Track: The ride system isn't going away... To me, I'd like to see them mix a little of the old with some new. Maybe split the attraction down the middle (one side of the track show how they tested and designed cars in the past...and the other side will show how they do it now or in the future). Same track...same ride...but it would showcase how far we've come and where we could go. I'd also close in the outdoor section with screen tech to make the cars appear to go faster.
9: Spine area behind Spaceship Earth: Make a two-story Carousel of Progress which has more scenes (center stage raises...and the seats rotate around). The inside of the walls will be circle-vision style screens and it will show the Future World spine area as it was during each time...and as the scenes change, the exterior would start to be built up to what we have today...and beyond)
10. Mexico: Coco themed. Really highlight Dia De Las Muertos.
11. Norway: This isn't changing...
12. China: Leave as is...
13. Germany: Add the Rhine River Cruise
14. New Country: Egypt
15. Italy: Leave as is.
16. American Adventure: Update show with new tech and ending
17. Japan: Mt. Fuji Coaster
18. Morocco: Leave as is
19. France: Leave as is (with Ratatouille)
20. United Kingdom: Mary Poppins dark ride...starting on a carousel horse, it then attaches to a track that brings you through the chalk-drawing countryside and finishes in a horse-race.
21. Canada: Leave as is
