Hi Janet!
Thank you for visiting the Moms Panel!
You can view the Magic Kingdom fireworks (Disney's Celebrate America) from the beach at Disney's Polynesian Resort, or Disney's Grand Floridian Resort & Spa. I have heard that in previous years you could only park at the resort parking lot on July 4th if you were a guest staying at the resort, or you had a dinner reservation there. From Disney's All Star Music Resort you can take a bus to the Magic Kingdom, then the monorail to either of these resorts.
If you wish to make a dining reservation, you can see a list of restaurants for
Polynesian here, or
Grand Floridian here. All reservations can be made
online, or by calling (407) 939 3463.
Enjoy the fireworks!
If you have any other questions, please come back and ask me - I would be happy to help you plan your magical vacation!
