Hi Frank! Thanks for bringing your question to planDisney.
Reserved fireworks viewing at Disneyland Resort is sometimes available with certain dining packages, which you can book in advance of your visit. For example,
Plaza Inn Dining Packages feature reserved seating for either fireworks or parades, depending on what is currently being offered. For the dates of your visit, it looks like the Plaza Inn Dining Package features reserved seating for the
"Magic Happens" Parade in Disneyland Park. This would include a meal and a voucher for reserved viewing access. The Plaza Inn on Main Street, U.S.A. in Disneyland Park is a classic dining location and the return of the beloved "Magic Happens" Parade is one of the best parts of the
Disney100 Celebration, so I think you couldn't go wrong with this choice.
However, it looks like your best bet for fireworks viewing would be the
Tomorrowland Skyline Terrace in Tomorrowland at Disneyland Park. I checked, and there's still availability during your visit. If you book on a night that features fireworks--check the
Entertainment Schedule for dates and times--you'll be treated to a great view. Of course, fireworks displays depend on weather conditions, which can change quickly. Because of this, fireworks can be canceled, but you'd still enjoy a beautiful nighttime view of Disneyland Park and a tasty dinner regardless. The current offering is Dinner in the Stars; you can check out the menu choices to see if it's something you'd like to try.
I hope you have a magical visit!
