Greetings Leslie!
My warmest welcome to planDisney! We’re delighted you brought a question our way!
I am so pleased that you are looking to upgrade your One Park Per Day
Theme Park ticket to include the Park Hopper Option. Doing so will allow you to experience even more magic! First, try the delicious Impossible Breakfast Sha-warm-up from Shawarma Palace at the all-new
Avengers Campus at Disney California Adventure Park. Then, in the evening, head over to
Star Wars: Galaxy’s Edge for the Felucian Kefta & Hummus Garden Spread from Docking Bay 7 Food and Cargo!
This upgrade will need to be requested in person at the Disneyland Resort Main Entrance Ticket Booth. And is subject to availability. I recommend checking the Availability Calendar to see if the Park Hopper Option is available on the date of your visit. If you are able to upgrade, you will start at Disney California Adventure Park and be able to hop to Disneyland Park at 1:00 p.m. You are not required to make an additional theme park reservation to visit the second park or hop back and forth between both parks. But, as always, theme park admission is subject to attendance availability as well.
Thanks again for your question. If you think of any more questions, don’t hesitate to submit them!
Tiffanie
