Hi Kelli,
Welcome to the Disney Parks Moms Panel! I think you will find the
Park Hopper Option gives you added flexibility to your park touring. Guests can select up to 3
FastPass+ selections for one specific park in advance. When you have used your initial FastPass+ selections, you may book an additional FastPass+ experience for a different park using your online app. You do not have to book 3 FastPass+ experiences in advance if you are only wanting to experience one attraction at that park.
Another strategy you may want to consider is to arrive early enough to the first park in order to ride the "must do" attraction via the standby entrance and book your FastPass+ selections for the second park. When my family "park hops", I usually book my FastPass+ selections for the second park that I will be visiting.
I hope this information has been helpful to you. If you have any additional questions, please don't hesitate to visit us again. Best wishes for a magical trip, Kelli!
Happy Planning,
Jodie
