Hi Venkata! Welcome to planDisney!
It sounds like you have big plans coming up when you visit the Walt Disney World theme parks soon! You must be so excited. You have chosen two great theme parks to visit.
EPCOT is my favorite, especially because of all the delicious dining options there, and Disney's Hollywood Studios is a blast with recent additions like Toy Story Land and
Star Wars: Galaxy's Edge. You are in for a wonderful day!
You can add the Park Hopper Option to your
Walt Disney World theme park tickets on the
My Disney Experience mobile app. When logged in on the app, touch the three lines in the bottom right-hand corner, then select "Tickets and Passes." On the screen that comes up, select the ticket you want to upgrade, then choose to change the ticket. You will then be walked through the process to change your ticket and you can choose to upgrade to a Park Hopper Option ticket.
Once your ticket is upgraded, all you will need to do is make sure that your Disney's Hollywood Studios reservation is still in place. No other
Disney Park Pass reservation is required! You only need to have the reservation for the first theme park you will visit and you must visit that theme park first. Then, when you want to park hop (any time after 2:00 PM), you can hop on over without another reservation.
I hope this helps, Venkata! Please let us know if you have any other questions.
