This is all getting so confusing! Our check in date is 11/30 and I was able to customize MB a few days ago. I should be able to check in online this Monday. So far so good, right? Wrong.

Last night I ordered our park tickets online (on the MDE site) and for delivery option, I chose standard mail. Now I can't link the tickets on MDE.
Just spoke to someone in tech support. If I had chosen the "will call" option for my tickets, I would have been able to link the tickets using the will call confirmation number. As it stands now, I have to wait until I receive my tickets (about fourteen days from now) then go to MDE and enter the number on the back of the actual tickets to link them on MDE. Only then will I be able to do FP+.
So, long story short, from what I can understand, if you plan on purchasing park tickets via MDE, choose the will call option and then you will be able to link your tickets and get FP without having to wait for the actual tickets in the mail. Hope that makes sense!
