Hi Kristina,
Thanks for visiting us at the Disney Parks Moms Panel! An unused ticket to the Walt Disney World Resort is definitely a great thing to find, and I'm happy to help you find out about its expiration!
If it was purchased before February of 2017, it likely does not have an expiration date other than it must be used within 14 days once activated. However, since you said it was a ticket from a recent visit, I'm guessing that it may have an expiration date. If you have a physical ticket, feel free to check the back to see if it has an expiration date, or if it's linked to your
My Disney Experience account, you may also check under "My Reservations and Tickets" to see if it shows an expiration date there. If it doesn't either place, I'd encourage you to call (407) 566-4985 and
talk to a friendly Cast Member who can hopefully help you find out if there is an expiration date for your ticket.
I hope this helps, Kristina, and I hope you have a blast using your ticket on another magical visit!
Missy
