Hi Sandy,
Welcome to planDisney and thank you for reaching out to us with your question about upgrading your Theme Park Tickets. I bet you are so excited to enjoy the magic at Disneyland Resort once again!
In order to upgrade your Theme Park Tickets, when you arrive at
Disneyland Resort, head to a Main Entrance Ticket Booth or Guest Relations location and a Cast Member will be able to modify your existing Theme Park Tickets provided there is still availability. I like to keep an eye on the
Theme Park Availability Calendar to see if my park days will be available just in case I need to make changes for any reason. If you would like some assistance with your specific Theme Park Tickets, I suggest calling
Ticket Services where a Cast Member will be able to help in real time.
I hope you have a wonderful visit to Disneyland Resort, Sandy. If you have any other questions please don't hesitate to come back and visit
planDisney again, we are always happy to help.
~Stephanie
