Hi Tillanie, welcome to planDisney!
I have good news! You can certainly change your reservations from December 25, 26, and 27, 2022 to January 2, 3, and 4 2023, but it will depend on a few factors. First, you will need to check your
theme park ticket's expiration date to ensure they are not expired. To check your ticket's expiration date, load up your
Disneyland Mobile App, click the three horizontal lines in the bottom right-hand corner and select "Tickets and Passes". You should see your tickets along with their expiration dates. As long as your tickets will not be expired on January 2, 3, and 4, 2023, you should be good to go.
Next, you will need to check the
Theme Park Reservation Availability Calendar to see if there is availability for
Disneyland Park on January 2, 3, and 4, 2023. If all looks good, you will need to cancel your current reservation by logging in to your
Disneyland Resort account, selecting the "My Disneyland" link, and then clicking the "Ticket and Reservation Details" link. Select the reservation you wish to cancel and click "Cancel Reservation". Once canceled, you're free to book your new reservation!
Thanks again for visiting us!
See ya real soon!
