For our trip last year I ordered our tickets online and received the physical tickets in the mail a couple of weeks later from Disney. This trip I ordered them in December and have not received physical tickets. We leave in less than 30 days. We are staying on property, have magic bands, and our tickets are linked in MDE. Do I need physical tickets in case something goes wrong with the link through magic bands? Or will guest services be able to deal with any issues without them?
