Transferal of Admission Media
Admission Media can not be legal transferred to someone else. Once someone has used a multi-day pass or an annual pass, that someone is the ONLY person that legally can use that pass on succeeding days. If you buy partially used passes, you probably won't get caught...but you're committing a misdemeanor in the State of Florida. That's not the kind of lesson you want your kids to learn, now is it?
Another example is that many people every day buy tickets from illegal vendors, having been told that they have 2 or 3 days left. When they come to the gate, they find they have NOTHING.
And that's what Disney does for the hapless folks. Nothing.
It is simply not worth the risk, and it's very unlikely you'll be able to find the con artist to get your money back. Besides, it is not fun spending 45 minutes talking to Disney security on why you're from Michigan trying to use someone's from Massachusetts. Disney knows all the info on that ticket, including where it was purchased.
Simply put, you can't buy and use previously used admission media, and you can't "share" admission media among your party...and you risk much if you attempt to do so.
