Epcot's popular IllumiNations: Reflections of Earth nightly firework show is currently running tests on preferred viewing being offered as a FASTPASS+.
There will be two priority viewing locations tested, one at the Germany Pavilion, and one at World Showcase Plaza.
It's expected that once the new FASTPASS+ is fully rolled out across the parks, guests will be able to choose their FASTPASS return times, as well as make FASTPASS reservations for shows, parades and events. This is part of Disney's "NextGen" system being rolled out across all the parks.
