Seriously, tho...
There should be an inclusion of World Showcase, and it's suppose to be fun, so...
Earth: SSE, The Land, The Seas, Journey of Water
People: World Showcase
Celebration: Festivals, World Fairs, performances, rides
Originality: Imagination, CommuniCore Plaza, Mickey & Friends, Dreamers Point
Technology: Spaceship Earth, Wonders of Xandar, Mission: SPACE
In a similar vain of nomenclature, I'd want to call all of former Future World as simply being World Celebration. If you're celebrating the World, you're celebrating nature and discoveries. There's no need for a separate World Nature and World Discovery, IMO.
Then we'd have simply World Showcase and World Celebration. And use "World's Fair."
And then we'd have
Epcot's World Fair
Featuring World Celebration and World Showcase
All Are Welcome to EPCOT!
Earth
Progress
Celebration
Originality
Technology
Then everyone would know what Epcot is about.
