Hello Leah! Thanks for visiting us here at the Disney Parks Moms Panel.
When visiting 2 parks in one day, you can only advance schedule your
FastPass+ selections for one park. At this time, you are not able to break the 3
FastPass+ selection choices up by park. If I were you, I would schedule all 3 of my
FastPass+ selection times for the first park. When visiting the second park for the day, head straight for the nearest
FastPass+ kiosk and select your next
FastPass+ experience. From there on out, you are considered to be using a rolling
FastPass+ which means you can only book and use one at a time from there on out. Please keep in mind, the F
astPass+ selection process is still considered to be in the testing phase and could change at any time.
If you have any other questions, please
feel free to ask me. Have a great day!
