Hello, Menchie! Thanks for stopping by planDisney and asking your question!
Most tickets purchased before the Disneyland Resort closed due to the pandemic were extended until December 16, 2021. You can view the full list of ticket types and their new expiration dates on the
"Theme Park Tickets and Reservations" page. Scroll all the way down to the "Modifications and Cancellations" section.
As of today, there are unfortunately no
theme park reservations available for the month of December. You can keep checking back, though, as availability may be added at a later date. If you aren't able to use your ticket before it expires, you can always apply the amount you paid for a wholly unused, expired ticket toward the cost of a new ticket at equal or greater value. You would just need to stop by a Disneyland Resort ticket booth to complete this transaction.
I hope this information was helpful. Have a magical day!
