Hiya Zebastian! Welcome to planDisney!
Oh boy! It seems like you are only hours away from the start of your magical Disney vacation! With the purchase of a
4-day Park Hopper Plus Option ticket, you'll be able to not only visit all four theme parks during your stay but also multiple visits to the water park and miniature golf courses!
Depending on what date you selected to start your tickets on, you'll have eight consecutive days to use them. You can make your park reservations for any day during this eight-day span. Even though you have already selected Disney's Hollywood Studios for your park day tomorrow, you can still make changes up until you enter the park on that day. Better yet, there is no additional charge to make this change. To do so, you'll need to cancel your current park reservation and then select the park you want for the next day. The system will not allow you to modify it at this time.
Before making any changes, you should check the
park availability calendar to make sure Disney's Hollywood Studios is available for this Saturday. I took a peek at the calendar and this park is not showing availability for this day, although this may change at any time. Since you purchased park hopper tickets, you can still visit Hollywood Studios starting at 2 PM on any of your current park days, as long as you visit the first park you made a reservation for that day.
When you do make it to Hollywood Studios,
Star Wars: Galaxy's Edge will be waiting for you! This immersive land has attractions, entertainment, dining, and once-in-a-lifetime experiences. You can spend an entire day just in this area of the park alone!
Zebastian, I hope some pixie dust comes your way and you can make the changes to the itinerary you are hoping for!
Have a magical day!
Greg
