Aloha June!
Thanks for stopping by planDisney with your question. It looks like you'll be having quite a travel adventure later this year to join in
The World's Most Magical Celebration!
If you add the
Park Hopper Option to your 2 day ticket purchase, you will be able to spend a little time in each of the 4 parks. You won't be able to see and do everything, but you will get to experience your "must do" attractions in each park. After you purchase your tickets, you'll need to make a reservation for 2 parks; the FIRST park you plan to visit each day. Since
Disney's Animal Kingdom typically closes earlier than the other parks I recommend making that one of your reservations, and then maybe planning to hop over to
Magic Kingdom for the second half of the day. Similarly, I might make a reservation to start in
Disney's Hollywood Studios on another day and hop to
EPCOT, mainly because I think you will love seeing
Harmonious, the new nighttime show around World Showcase in EPCOT. Plus, EPCOT has a lot of great dining options for a wonderful dinner.
Of course, which parks you choose to visit each day doesn't really matter. You'll have a wonderful time wherever you decide to go. Just make sure to select the 2 parks where you plan to start each day. On the day of your visit, you'll be able to hop to a different park without a reservation at 2:00 PM (or whenever park hopping begins) as long as you've checked in to the first park where you reserved.
Hope this helps. Have fun planning your magical vacation!
