So we have stacks of unused non expiring park hopper tickets. We used to buy them and use majority, but when they only had a couple of days here or there would save them because a single day ticket costs so much. that way we could piece together what we needed. Probably 3-5 years ago Disney stated that they tyvek or swipe tickets needed to be converted to the rfid ticket. So we went to guest services to have them converted, it was quite an ordeal to straighten out all the benefits left on each ticket. They had to manually check each tickets usage, then load new tickets. Two of our tickets were on our MDE and were accidentally used when bought annual passes. So last week while in the park we had to get that worked out. Long story short, all of our tickets were converted to "new" tickets, but have expirations of 2099 to give them the quasi non expiration benefits. It also means I can't see what was printed on the tickets, but even when they reissued our mistakenly used tickets, the CM's were talking about ticket changes coming and were making notes on our account to help other CM's in the future understand what the tickets were in case there was a problem. Because when the system is updated it impacts all tickets out there and the system does not recognize an old versus new ticket.
