Hi Veronica, welcome to planDisney!
Thanks for bringing your question to us, I can help!
First and foremost, we need to check the
Theme Park Reservation Availability Calendar to see if there is reservation availability on November 29, 2022. I just took a peek, and I see availability at both parks for
Park Hopper Tickets and reservations for just Disney California Adventure Park for the
1 Park Per day Tickets.
If that works for you, then you can move forward to the next step, which is to cancel your current theme park reservations. You can do this by logging in to your
Disneyland Resort account, selecting the "My Disneyland" link, and then clicking the "Ticket and Reservation Details" link. Next, select the reservation you wish to cancel, and click "Cancel Reservation". You'll then be able to select the party members who need to cancel. Once canceled, you're free to go ahead and book your new reservation! You can do this by going back to the "Ticket and Reservation Details" link, and selecting "Make Park Reservation".
I hope that helped, and if you have any other questions, please visit us again!
See ya real soon!
