Hi Jessica,
Welcome to the Disney Parks Moms Panel! It looks like your Walt Disney World Resort vacation is coming up so soon! The ticketing rules for Walt Disney World Resort Theme Parks recently changed so I spoke to a few Cast Members to be sure I would be giving you the correct information.
If your tickets were purchased before October 16, 2018, then you don't have to worry about changing the dates you plan to use the tickets. You will need to use them before their expiration date and the tickets will expire 14 days after first use.
If you purchased your tickets on or after October 16, 2018, you can change the dates in
My Disney Experience. There should be a link under the Ticket that will allow you to change the dates. If the link does not show up or you have any problems with it, I suggest calling (407) 939-1936. They should be able to help you reassign the dates for your tickets.
Jessica, thank you for visiting us with your question. I hope you'll let us know if we can help you with any other questions!
Wishing you a magical visit,
Amy H.
