To clarify, my understanding is that you can buy the APs now and you have a year to activate them. You activate them by going to one of the parks (I think there's a place at Disney Springs that can also activate them).  Once you activate, you have 365 days to use them.  Out of curiosity, is there a way to activate them without being on site?
I learned this just a couple days ago, and it's so clutch because we want to buy passes, but we know we won't use them for a couple months at least.  So we can still get the gift card promo.  Hooray for discounted dues!
