I purchased my park tickets online, made my FP+ reservations and ordered my Magic Bands on the same day. The Magic Bands arrived last week, and I also received an envelope containing "ticket media" (i.e., cards). Last year when I ordered tickets and Magic Bands I only received the Magic Bands, but I don't remember whether I ordered them all on the same day. Does the fact that I received separate tickets mean that my tickets aren't on the Magic Bands and I'll have to do something once I get to the resort? Or if the tickets are linked on MDE (which they needed to be for me to make FP+ reservations) will the Magic Bands be good to go? We're going at Christmas time when it's really crowded so I don't want any holdups at the parks.
