Hello, Lakesha!
Welcome to the Disney Parks Moms Panel! We are delighted to answer your question regarding your upcoming
Walt Disney World vacation!
If the tickets you have from 2001 were
purchased with the non-expired feature, then these Disney Theme Parks tickets will still be valid. Now, there are some things to know about these tickets. Each Disney Theme Park ticket is assigned to a specific person. If you are not the adult assigned to this adult ticket, you will not be able to use the unused portion of the ticket. From your question, it looks like the two child tickets you have would be attached to your nieces. If that is the case, those tickets could not be used by your seven-year old.
If the adult ticket you have was assigned to you and you had purchased the non-expired feature, you can use this one-day ticket for a Disney Theme Park! When you arrive, please make your way to Guest Services right outside each of the Disney Theme Parks. You will then have the opportunity to explain your situation with a Cast Member to convert your old ticket into a current ticket.
If you have other questions, please let us know! We are here to help in any way!
Have a MAGICAL day!
Wes
