My sister and I are going to be going to be going to WDW for a couple of days in September. She had already purchased her ticket from an outside, well known vendor and I just bought my 2 day, PH from Disney. I have a MDE history and my ticket is now registered within it. Now to my question. Can I link her ticket to my account so I can set up FP's plus a possible dining stop to my account including her in my MDE? I tried reading about it, but it might as well have been in Latin. All I want to do is simply add her in and then make whatever reservations I can for the two of us simultaneously. At this point other then recording my ticket nothing has been chosen.
