My husbands boss dug out some old disney tickets he had from his family trip in '89 and gave them to my family. They are 5 day park hoppers with 2 days left on them. How does using old tickets with the stamps work today? Do they give you a new ticket in exchange? If you use the tickets up do they take them from you? They are in mint condition and I would like to be able to give them back to my husbands boss for sentimental value( I would love to frame them as a collection item). Any idea how this works?
