Hi Megan, welcome to planDisney!
The great thing is Guests can update their
theme park reservations easily from within their
Disneyland Resort account, and I'm happy to walk you through the steps! I just checked the
Theme Park Reservation Availability Calendar and there is full availability for November 28, 2022, so you should be good to go!
First you will need to cancel your current theme park reservation. 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. Select the reservation you wish to cancel and click "Cancel Reservation". Once canceled, you're free to go ahead and book your new reservation! Just head back to the "Ticket and Reservation Details" link and select the "Make Park Reservations" link.
If you have any more questions, please do visit us again!
See ya real soon!
Jin
