I love EPCOT!
Park is divided into two parts:
Future World is the section of the park closest to the entrance. The first thing you see upon entering the park is the parks Icon, Spaceship Earth. The remainder of Future World radiates out from a central point which is the Fountain of Nations that is located directly behind Spaceship Earth. Surrounding the Fountain of Nations are Innovations East and West which house a showcase of new technologies (well, they are supposed to. Both are a bit outdated, but there is some updating in progress I believe), as well as club cool (free samples of Coca Cola products from around the world) Starbucks, the Electric Umbrella (counter service) and Mouse Gear (the biggest gift shop in EPCOT). Beyond the curved buildings holding those, there is a ring of walkways, lawns, gardens, and water features, as well as a monorail loop, and then outside of that are the pavilions of Future World. To the left are The World of Energy, Mission Space, and Test Track. To the right are The Seas, Imagination, and The Land.
Past Future World is the World Showcase. The World Showcase is built around a lagoon. The pathway around the water is about 1.2 miles long in roughly a circle. Around the circle are 11 pavilions, each representing a different country of the world. Two of the pavilions (Mexico, and Norway) have rides in them. All of the pavilions feature architecture, food, beverage, and merchandise representing their country. A number of the pavilions also offer up some kind of entertainment again representative of their culture, and several also have some kind of museum display.
Future World opens at 9:00 when the park opens. World Showcase (with the exception of a couple of food service locations which open at 9) opens at 11:00.
Every day at EPCOT ends with Illuminations, a show of lights, lasers, fireworks, fire, and music, performed on the World Showcase Lagoon. Illuminations is probably my favorite night time show at Disney World!
