Examine your ticket to see what type it is. It will likely be either a Magic Your Way ticket or a Park Hopper pass. Park Hoppers were discontinued in 2005, but the extra days on it may still be good. Magic Your Way tickets were issued after 2005 and normally have a 14-day time limit from the day they were purchased. If the Magic Your Way ticket has a No Expiration option on it, then the limit is rescinded and you can use the days at any time. If your ticket is neither Magic Your Way or a Park Hopper, it predates the year 1996. You can still redeem days if any are left on it, but you’ll need to convert the ticket to a new medium.
Call Disney Ticketing at 407-566-4985. They are open Monday through Friday, from 9:00 a.m. to 5:00 p.m. Eastern time. Have your ticket ready with all of the information on it. When you hear your list of options, press “2,” then follow the directions. Disney World doesn’t always offer this option, but if the service is running, they should tell you whether or not you have any days left. It’s the only way of doing so that doesn’t involve going to the park itself.
Visit the Guest Relations window at any of the four theme parks at Disney World (Magic Kingdom, Epcot, Disney’s Hollywood Studios or Disney’s Animal Kingdom). They will tell you how many days you have left on your tickets, and upgrade any older tickets to fit the modern Magic Your Way format. If you have a Magic Your Way ticket and you’re staying at a Disney hotel, talk to the concierge in the lobby; he or she can scan your ticket and tell you how many days are left on it.
