Hi Billy!!!
I love staying at Disney's Pop Century Resort!!! Nighttime in the theme parks is so magical!! I cannot think of a better way to end a day in the theme parks than by watching a wonderful parade, show, or fireworks display!!!
Other than the Magic Kingdom, there are two other theme parks that offer a nighttime entertainment experience. Epcot offers
Illuminations: Reflections of Earth nightly in the World Showcase Lagoon. This is a stunning show involving fireworks, lasers, and fire!! There are prime viewing areas around the entire World Showcase. Disney's Hollywood Studios offers
Fantasmic which is an unbelievable show involving live action, fireworks, water screens, and more!! It is probably my favorite show at Walt Disney World!!! Fantasmic runs most evenings in the Hollywood Hills Amphitheater and will often times fill up, so you are encouraged to arrive at the theater at least 30-45 minutes in advance of showtime. Disney's Animal Kingdom does not have an evening show since it closes early to accommodate the schedules of the animals.
If a theme park has Evening Extra Magic Hours, the nighttime shows are not affected. They will usually run their normal schedule each evening regardless.
Please let me know if you have any additional questions!!
Have a magical trip!!
