Hello there, Shinhyuk! Welcome to planDisney. We are so glad you've stopped by with your ticket question for us.
Your visit to Disneyland Resort is just days away! I hope you and your party are getting excited. Unfortunately according to the
eTicket Terms and Conditions, tickets are non-refundable and so you would not be able to switch your tickets. Sometimes ticket upgrades are possible if you are wanting a ticket that is greater in value or a Magic Key pass, but this would not qualify as that. I will also note that when you upgrade a ticket, you will lose your theme park ticket reservations and need to make new ones with the new ticket. I see you are planning on visiting on July 4, 2023, and at the time of writing this, the
California Ticket Resident Offer tickets do not have any reservations available for that day. It looks like it is a popular day to visit so I would keep your tickets and enjoy the parks.
If you are looking to rest your legs and be entertained, don't miss
Rogers: The Musical which just debuted at the Hyperion Theater in Disney California Adventure Park this week. There are multiple shows each day and you can use the Virtual Queue in the Disneyland app to get a spot for you and your party.
Shinhyuk, I hope you have a wonderful visit to Disneyland Resort this week. See you real soon!
Carrie
