Hi Emerald, welcome to planDisney!
I am happy to walk you through the steps of locating the expiration date of your
theme park tickets! I found that the easiest way to do this is through the
Disneyland Mobile App. So please download the Mobile App and sign-in to your account. Then 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 don't see your tickets there, then you'll need to link them to your account. You should see a "Link Tickets & Passes", and that should take you through the steps to link your tickets. Once your tickets are linked, you should see your tickets there along with their expiration dates.
Now if your tickets happen to be expired, don't worry because 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 news right? Just visit the
Disneyland Resort Main Entrance Ticket Booths, and the fantastic Cast Members there can certainly help you out!
See ya real soon!
