Hi there, Danelle!
I just stayed at Disney's Beach Club Resort last month and had such a fantastic time! You can see the tips of some of the fireworks in
Illuminations: Reflections of Earth from the beach, but I would recommend watching it at least once while you're in Epcot so you are able to really enjoy the whole show, it's pretty amazing! There might be a few rooms on the top floors of the
Disney Vacation Club Villas section where you could watch from the balcony with a pretty decent view of the fireworks.
There are movies played on the beach most nights at Disney's Yacht & Beach Club Resorts! When you check in, you'll be given a schedule of things going on at the Resort, and the movie schedule will be on there. They typically play a different movie each night in case you'd like to join more than once during your vacation! You can even bring snacks if you want! Last time, we watched Tangled with our friends and the lantern scene was just gorgeous on the big screen with that magnificent view of the Boardwalk just across the water!
I hope you have an amazing time, Danelle! Please don't hesitate to come back and visit the Moms Panel if we can help with any other questions you think of!
Have a Pixie Dusted day!
