Hey Taylor!
A very warm welcome to planDisney and thank you very much for dropping by with a question!
It’s a simple process for you to adjust your starting
Disneyland Resort theme park as long as there is availability on your desired dates for your ticket type. To modify your
Theme Park Reservation, please log in to your Disneyland Account select "My Disneyland" then click "Ticket and Reservation Details" and select "Cancel Reservation." After you receive the confirmation of cancellation, you will be able to book a brand new theme park reservation for your desired date. Theme Park Reservations are limited and subject to availability. Before you attempt to change your reservation, I recommend checking the
Availability Calendar to make sure your desired date and theme park are accepting reservations for your ticket type. If not, don’t lose hope! Keep checking the calendar as availability changes frequently as people cancel their Theme Park Reservations.
I hope this helps! Please come back to planDisney if you have any more questions!
