Hello Akeisha! Thanks for bringing your question to planDisney! A visit to the Walt Disney World Resort on the 4th of July is a great way to celebrate the holiday!
In order to be admitted into any of the four Disney Parks, Guests ages three and older must have both a valid theme park ticket and a
Disney Park Pass reservation for the park they wish to visit. Because your little Mouseketeer will be turning three prior to your visit, she will be required to have both the ticket and the reservation.
Ticket charges for children ages three to nine years old cost slightly less than ticket charges for Guests ages 10 and above. Prior to purchasing a ticket, you can check the
Disney Park Pass calendar to see which parks still have availability for the upcoming holiday. I just took a quick look at the calendar to find that both EPCOT and Disney's Animal Kingdom currently have park availability on the 4th of July!
I hope this information is helpful as you continue your planning!
Hakuna Matata! Jonathan
