I don't believe so...since they switched to that magnetic strip, it's been tough to tell, and created more scams for people to sell...call the ticket line to ask for sure...
Yep, only at the parks, no hotels, or at downtown Disney. Only the 4 major parks. I was lucky enough to get a hand over the phone by a very nice CM, but this seems to becoming more and more unusual as the time goes along.
Old tickets can be scanned at all major park Guest Relations, at Guest Services at the resorts as well as at your Disney resort front desk and at either of the two Guest Relations locations at DTD.
My mistake than, I was told by the person at corporate only at the 4 parks, but she may have been making me feel better that she was helping me Sorry for the mis info.
