Hi Anabel, welcome to planDisney!
I have GOOD NEWS! You can reschedule your reservations as many times as you want, as long as your
theme park tickets are not expired. And it's really easy to check your ticket's expiration date. Just hop into your
Disneyland Mobile App, click the three horizontal lines in the bottom right-hand corner and select "Tickets and Passes". You should see your tickets along with their expiration dates.
If you're ready to change your reservation date, you will need to cancel your current reservation first. 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!
If you're unsure of when you want to reschedule your reservation to, there's no hurry! Just keep an eye on the
Theme Park Reservation Availability Calendar to ensure the dates you are interested in are available.
Hope that helped!
See ya real soon!
