I have seen mention that passes can pretty much always be upgraded, but I don't know the details. We've never done APs before but hope to be visiting more often so we thought we'd like to try it this time (plus probably get the TIW dining card). We've already purchased 7 day park hopper passes. So, when we get to WDW, can we upgrade to annual passes (with the DVC discount) at some point? Would we have to do it right away, or anytime during our stay? If we waited until we had been using the PHs for a few days, and then upgraded, what would be the AP expiration date? 365 days from the first use, or the date we upgraded? And what would be the cost?
Hope these aren't dumb questions...TIA!
