Hi Mariela ~
While fireworks are amazing to see, I completely understand that some Guests have a sensitivity to the sounds. Ear plugs are not provided but you are welcome to bring your own ear plugs or headphones to reduce the noise.
If you're inside the Magic Kingdom during
Happily Ever After, there are a lot of shops and restaurants throughout the park you could go into during the fireworks. I'd suggest a location near the very front of the park as the fireworks are launched near Cinderella Castle and in the back of the park. There are shops along Main Street, U.S.A. and Town Square Theater is located in the very front of the park. Happily Ever After is an 18 minute show so plan to be in a show or attraction during that time. You can find the schedule for shows on the Times Guide as you enter the park or on the
My Disney Experience mobile app.
If you want to see Happily Ever After as far away from the sounds as possible, there are places outside the Magic Kingdom to view the fireworks. The
Pirates & Pals Fireworks Voyage is a great way to see the fireworks without being near the sounds of the fireworks. There are also great viewing locations for Guests staying at the Grand Floridian and Disney's Polynesian Village Resort. You can't see the projections on Cinderella Castle (which are a big part of this show) as well from these locations but you still get a great view of the fireworks.
Just so you'll know, Mickey's Royal Friendship Faire at the Magic Kingdom does have a couple of fireworks at the end of the show and it's held a few times daily.
Wishing you minnie magical memories :-) Allison V.
