Hey Tyanne! I completely understand where your daughter is coming from. My son wasn't a fan of the loud fireworks noises for a long time. Those fireworks are beautiful, but they can be so loud, even with ear protection. I’m glad she’s feeling ready to try again this trip!
My son discovered that riding attractions like
Seven Dwarfs Mine Train, T
he PeopleMover, or
Big Thunder Mountain during the fireworks let him catch glimpses of the show without having to deal with the loud, continuous noise.
There isn't really a quiet spot inside Magic Kingdom, since the fireworks launch near the Cinderella Castle.
I'd suggest watching from a distance. Consider watching from the beach at
Disney’s Polynesian Village Resort or the boat launch or the patio near
Gasparilla Island Grill at
Disney's Grand Floridian Resort and Spa. It’s peaceful, the music is piped in at a lower volume, and you still get a lovely view across the lagoon.
I hope this helps, and I really hope she has a great experience this time!
Toodles,
Korliss
