Hello Gary, welcome to the Disney Parks Mom´s Panel!
I am happy to inform that Walt Disney World honors all unexpired
theme park tickets with remaining admission days.
Your 2013 theme park tickets expire 14 days after their first use. In other words, your theme park tickets will be valid in 2014, until you start using them. Once you start using your tickets you have 14 consecutive days to use all your admissions.
Tickets with the No Expiration Option will never expire - this option is for an additional fee.
So do not worry, enjoy your vacation and a merry Christmas to you all.
Thank you for visiting and hope to hear again from you.
Miguel
