Hey Edmond! Thanks for stopping by planDisney with your question.
I know the new park pass reservation system can be a little confusing. At this time, you will only make a
theme park reservation for the park you want to BEGIN your day at. Then, starting at 2pm, you can park hop to any other park, as long as there is availability (I have never seen my second park NOT available).
For our upcoming trip, I have multiple theme park reservations for Disney’s Hollywood Studios, with the intent of going there for the morning, and then taking the
Skyliner over to EPCOT for the afternoon and evening, since there is always an abundance of delicious food options at EPCOT.
I hope this helps for planning your March trip to The Most Magical Place on Earth.
Happy Traveling,
Tracy
