That's not what we were told. Maybe the difference is we have 6 day military tickets from 2020, we've used one day but there are five unused days. The current tickets we have are set to expire in September. DD went to the base ticket office, they told her to call Disney, Disney told her to go to the base. She spent hours on the phone with Disney and finally they told her to go to Guest Services when we arrive.
Tweetykl - we are a three hour plane ride away so I guess we will have to stop at GS on the way in to the parks. Maybe it is different with unused tickets?
