Hi Priscilla, welcome to planDisney!
I'm so sorry to hear that you might not be to attend your trip to The Happiest Place on Earth! Unfortunately,
theme park tickets are nonrefundable, but I do have some good news! You can reschedule your reservation to another date as long as your tickets are not expired. To check your ticket's expiration date, load up 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.
Now if in the worst case your tickets happen to expire, not to worry, you still have options! Per
Disney's eTicket Terms & Conditions, any wholly unused, expired Disneyland Resort theme park tickets (except for special event tickets or tickets purchased from a third party), can be applied towards the purchase of a new theme park ticket in equal or greater value to what was paid for the original ticket! Great right?
I truly hope you're able to find another date that works better for you!
See ya real soon!
Jin
