Hey there, Jeanette! As a Mom whose kids will be 9 and 11 on our next visit to the Most Magical Place on Earth I appreciate this question and am happy to offer up my opinion.
Jeanette, I love adding in extra pixie dust to our vacations when I can, so let's talk about options. I'll first encourage you to check out
THIS PAGE of Enchanting Extras. Now that my kids are a bit older, I think we're going to try out the
Ferrytale Fireworks: A Sparkling Dessert Cruise or maybe the
Celebration at the Top: 50th Flavors & Fireworks at Disney's Contemporary Resort. Both of these pair a unique viewing of fireworks with sweets and treats!
Jeanette, it's also possible that closer to the 4th of July other options or themed events will be released, but as of now, we don't have any information regarding additional activities. If any of the Enchanting Extras look like they would put smiles on the faces of your Mouseketeers, booking begins 60 days in advance of your stay, so make sure to revisit that page closer to time of your trip.
I hope this helps as you're thinking ahead to summer at the Walt Disney World Resort. Please come on back to planDisney with any additional questions.
Lauren
