Ahoy there Tierney, and welcome aboard planDisney!
Shiver me timbers! It looks like you have some treasure on your hands.
Walt Disney World theme park tickets with remaining admission arrrrr more valuable than Captain Jack Sparrow's pirate gold.
Any unused days on
tickets purchased before 2004 are still valid, and once you link them to your
My Disney Experience account, you'll be able to make reservations in the
Disney Park Pass System. While logged in to your My Disney Experience account, select "My Plans" and choose "Link Reservations & Purchases" from the "Add More Plans" dropdown menu. Click on "Link Tickets," and scroll through the options to the right to find your ticket type. See if you can find an image that matches the ticket you have, and enter the numbers shown.
If you don't have any luck on your own, you might need to
give the friendly folks at Disney a call at (407) 939-5277. You can also send an e-mail to ticket.usage@disneyworld.com and a Cast Member will assist you. Be sure to provide as much information as possible about your ticket, including front and back photos.
I hope this is helpful, Tierney, and that you experience smooth sailing on your upcoming adventure. If there's anything else we at planDisney can do to make your journey even more magical, don't hesitate to reach out again.
Wishing you and your crew a happy holiday season,
Betsy
