You will get them at some point. Ours did not come immediately, but they did eventually show up to be customized on-line, and then it took a couple of weeks for them to arrive. This is probably in your favor since the new Magic Bands are coming soon, but are not here yet.
If you still have the Magic Bands you used last Oct, they should still work. Or when you make your next reservation, you will get some then, too. The AP bands will be in addition to all the others, but they all do the same thing. If you look carefully in the box before you throw it away, they should have AP sliders, but are otherwise the same.
If you need them right away, I would call Member Services. If you are already there, try Guest Services at the parks, or you can get the generic ones at your resort - gray, not customized. As a
DVC member, the casual pacing of the delivery did not bother me, but if I was a Florida resident, I would be trying to get them as soon as possible!
