Epcot’s nightly performance of Illuminations is one of Disney’s best shows. It begins at the parks scheduled closing time (usually 9pm), and is visible in all the areas around the World Showcase Lagoon. You will see people securing spots around the lagoon beginning over an hour before the show. Disney also sells tickets to premier viewing locations, including ones on boats right on the lagoon.
The show includes laser, light and smoke features and grand firework displays. The combination of these effects and the music accompanying the show are quite compelling. Be sure to stay for the Illuminations performance whenever possible. During holiday seasons, the finale of the show is altered slightly.
