You can change the date to as far out as WDW is currently selling tickets... which right now is through December 2024. If your next trip will be after that, I suggest making note of the ticket number and value for future reference. Once expired, the ticket will disappear from your view in MDE but CMs can find it -- having the ticket number and knowing the value helps. Once WDW is selling tickets for your new dates, you can call to upgrade the expired ticket to the new dates and pay any extra due.I checked my company, Boardwalk Ticketing, and it said no refunds, but I can change the dates. We only go to WDW every two years so can I change it to that far in advance?
