Soarin' is my favorite attraction. Epcot as a whole is our favorite Park. We spend the majority of our trips in Epcot and still don't "do it all" Just in the Land alone, there are 3 attractions. Then Test Track, Mission:Space, Ellen's Energy Adventure, Spaceship Earth, The Living Seas with Nemo, Turtle Talk, Journey into Imagination, Innoventions Club Cool, Kidcots....that's all just in FutureWorld.
Then in World Showcase, you have all the countiries, Gran Fiesta, Maelstrom, the American Adventure,Kim Possible, the movies in China, France & Canada, Mo'rockin, Off Kilter, British Invasion, the different shows & streetmosphere in each country, Illuminations....
It's more than we've ever been able to do in one trip.
Just slow down & don't focus on only the big E Ticket Headliners, there's tons of little stuff that's just as good.
