Greetings, Rene and welcome to planDisney with this excellent question - thank you!
Your
Walt Disney World Resort vacation is almost here, how positively exciting that is! Best of all you’ll be in time for the 50th Anniversary Celebration to mark this milestone at
The Most Magical Place on Earth!
The way the
Disney Park Pass - Theme Park Reservation system works at this time is that Guests
must visit the first-reserved theme park and then anytime after 2:00 PM Guests may visit a second theme park, pending availability, without a Theme Park Reservation. As well, in order to secure a Disney Park Pass - Theme Park Reservation, Guests need valid
Walt Disney World Resort theme park admission, and in this case, to park hop you will also need the
Park Hopper® Option on the tickets, to save using an extra day’s theme park admission.
If I am to interpret your question correctly, Rene, if you plan on starting your day at Disney’s Hollywood Studios you will need a Disney Park Pass - Theme Park Reservation for this park, and then your first
Disney Genie+ service selection would have to be for a Lightning Lane entrance attraction at Disney’s Hollywood Studios.
Rene, if you wish to select an arrival window for a Disney Genie+ service attraction at 7:00 AM at Disney’s Animal Kingdom Theme Park, then your Disney Park Pass - Reservation would have to be for Disney’s Animal Kingdom Theme Park.
Guests must visit the first reserved theme park first, and then visit a second theme park only after 2:00 PM, pending availability. I hope this doesn't cause any disappointment, and if I misunderstood your question kindly accept my sincerest apologies.
It might be easier for you to book your Disney Park Pass - Theme Park Reservations as soon as possible and then wait to add the Disney Genie+ service on the very day of your reserved theme park visit anytime after midnight on the day of your reserved theme park visit, pending availability, to be ready to make your first selection at 7:00 AM.
