Hello Jennifer!
A very warm welcome to planDisney! Thanks for dropping by with a question!
If your plans change, don’t worry! It’s very easy for you to adjust your dates and take your magical vacation to the
Disneyland Resort when the time is right for you! 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. This change must be made by 11:59 p.m. Pacific Time on the day before your visit. If you wait until the day of your Theme Park Reservation, you will be unable to modify it.
I hope this helps! Please come back to planDisney if you have any more questions!
Tiffanie
