Hi there, Pat!
Welcome to planDisney! Thank you for stopping by with your question for us.
Three chEARs! You’re going to The Happiest Place on Earth, and that’s certainly worth celebrating! If you haven’t already, I hope you check out @planDisneyPanel on Instagram to follow along on all the magical adventures during Disneyland Resort's
reopening!
Pat, Under the Important details section of
Theme Park reservations, states, “Theme park reservations cannot be modified but can be canceled by visiting My Theme Park Reservations. If you’d like to cancel an existing reservation and book a new one, please first check on the availability of reservations for your new desired date and/or park.” Although you cannot modify your current reservation, if you cancel it, you can make a new one.
However, before you cancel your current reservation, I would encourage you to first check for
Theme Park Availability for the date you would like to visit to ensure there is availability at
Disney California Adventure Park for the date you’d like to visit. If you find it shows availability, you can most certainly cancel your current reservation to make a new one for the theme park.
We can’t wait to welcome you to the magic, Pat! Have an enchanting time.
Aena
