Hi Casey!
Thanks for bringing your question to planDisney! There's no better way to celebrate a birthday that with a trip to the Most Magical Place on Earth! Your son will have a memorable time enjoying the attractions and experiences that only a visit to Walt Disney World can provide! Be sure to pick up a Happy Birthday button at Town Hall in Magic Kingdom or Guest Services at the other theme parks. Your son will have a wonderful day with all the Happy Birthday wishes he'll receive from both Cast Members and guests alike.
Casey, in order to spend the day at your theme park of choice, you must be sure to have an valid theme park ticket, and make a reservation on the
Disney Parks Pass system. In order to ensure social distancing and the safety of guests and Cast Members, Disney has implemented the Disney Parks Pass system. You will need to go on your computer, and under the
My Disney Experience, select make a Disney Parks Pass reservation. According to the
Disney Parks Pass reservation calendar, all parks are available for September 21st, so I would try to make those reservations as soon as possible.
Hope this helps you plan your magical vacation, and a great big Happy Birthday from us to your son!
Malanie
