Looking at a map of the park and I will follow it around with my "wish list" and a few suggestions.
Spaceship Earth - Just keep updating it as needed. This is like a moving version of HoP at MK which makes it informative, and like a ride! Now, what are those Romans discussing...
UoE - TT and MS are rides, so make a ride here already! Same with the unnumbered and off the map WoL. I like browsing through it during the Food & Wine Fest, but that can all be moved somewhere else.
MS - I ruined a whole day back when if first opened by going on this ride, but my son likes it and he like to challenge others to ride it with him. Keep it for the foreseeable future.
TT - I like it as much and don't like it as much as the original version, which is still good enough to ride it every trip at least once, sometimes twice. It is better when the tech is all working. Keep it working and it is good for 15 more years.
Innoventions - I think this is a necessity in EPCOT because of what it does, and what EPCOT is about. Keep it, but keep updating and changing the displays and interactive tech out as needed.
Character Spot - A necessary evil to keep the right people happy. Is all of this building being used now, though?
The Seas with Nemo - I liked SeaBase Alpha, the movie, the focus on sea life as it was, but Turtle Talk makes up for the change, for now.
The Land - I love Soarin'. So does my daughter. The wife and son like it enough to ride it with us. It does need to be re-themed for Florida and the equipment needs to be upgraded. I want to throw this out, however, that if ST can have a variety of changing experiences, with an upgrade in equipment couldn't Soarin' as well? Living with the Land is educational, and a water ride! Keep it, but do something with the Circle of Life.
Imagination - Redo. Keep it in step with The Seas and The Land with... *drumroll please* The Skies! Make a new queue for Soarin' coming off of this area. New 3d movie for Captain EO (my kids will be like it now, but it needs to change), air themed. And Journey into Imagination can keep a newer, kick butt version of Figment with Dragons!, the ride.
Mexico - Good first stop or last stop for traveling the WS. Has a water ride, so it is set.
Norway - Bring back the ship! Akershus and the princesses another necessary evil. Yes, get rid of the movie after the ride. Water ride 2, right next to the other water ride.
China - Needs more people. TSMM type ride defending the great wall against the Huns!
Outpost - Aaaaaahhhhh! Why, why, why? First place to build a new country pavillion. Something South America like Brazil (another steakhouse!), with a gaucho ride (carousel).
Germany - Add a new Octoberfest ride! Good to go otherwise.
Italy - Great restaurants, nice architecture, needs a IASW like Renaissance ride.
American Adventure - More concerts! Need a big wooden coaster and more of a boardwalk feel to it.
Japan - Love the shops, but they don't change the inventory out enough. More giant robots and other toys (or should this be in China where these things are made?). I like the Mt. Fuji 'mountain' coaster idea, yet I think a Godzilla type ride with the IoA Spidey tech would work also.
Morocco - I like the way it is, and the waterfront restaurant should add to it. My son still hates us for giving him lamb and him liking it until we told him what it was. Magic carpets with Dinosaur tech.
France - Nice addition/change with Les Halles Boulangerie and Patisserie. Eiffel Tower Fear Fall anyone?
*insert*- The 'island from France, along with the land NW of it at the end of the bridge all expanded and make it Australia. 20,000 Leagues Under the Great Barrier Reef would do well.
United Kingdom - More restaurant space. I like a Mary Poppins a la Peter Pan ride here. Or Doctor Who.
More contemporary culture gifts in the shops as well. I need a better TARDIS than what I can find already.
Canada - Expand the shop. Build a hockey rink.
FOR THE FINALE! - Build a mock-up of the International Space Station over the World Showcase Lagoon. Have a lightshow play off of it, and make the fireworks more visible from around the World Showcase.
