Hi Elena, welcome to planDisney!
Thanks for bringing your question to us, I can walk you through the process of updating your
theme park reservations!
Please know that to change your current reservation, you will actually need to first cancel your current 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 can then move forward to book a new reservation.
But before you cancel your current reservation, please check the
Theme Park Reservation Availability Calendar to see if reservations are available for your desired date and theme park. ALSO, another warning to keep in mind, even if a reservation is available on your desired date and theme park, there is a chance that the reservation will get booked by the time you cancel your current reservation and try to book a new one. AND, once you cancel your current reservation, it is canceled, and another Guest will be free to pick up your reservation. So please keep all of this in mind before you cancel your current reservation.
If you have any other questions though, please visit us again!
See ya real soon!
Jin
