Hi there Michelle,
Welcome to planDisney, we are so happy you took the time to stop by with your question! It looks like you will be visiting Disneyland Resort soon, doesn't the
Avengers Campus look incredible? I can't wait to experience
WEB SLINGERS: A Spider-Man Adventure and help save the Campus!
Since you have your Theme Park Ticket, the only way to add the Park Hopper Option at the moment is at any of the Disneyland Main Entrance Ticket Booths or Guest Relations locations, provided there is still availability. Keep an eye on the
Theme Park Reservation Availability Calendar for the most up to date information regarding capacity, it could help gauge if you will be able to upgrade your Theme Park Ticket to include the Park Hopper Option. If you are worried that you won't be able to upgrade, you could always purchase a second One Park Per Day Theme Park Ticket to visit Disney California Adventure Park or you could also purchase another Theme Park Ticket with the Park Hopper Option for your preferred date and use your other Theme Park Ticket for another day prior to the expiry date. Either way, it's a great decision because it means more time at the Happiest Place on Earth for you!
I hope you have a fantastic visit to
Disneyland Resort Michelle. Please feel free to send us any other questions you may have, we are always happy to help.
