We just got back on Saturday-- had 1 day base tickets with our Visa
Free Dining package and upgraded to annual passes (we always get APs), We had a horrible time doing it-- be careful on this! We were told by several CMs at WDW that we HAD to do this before we departed-- we couldnt 'save' and do it later. We also had one CM tell us we couldnt upgrade to APs until the day we left-- that we had to upgrade to however many days tickets, then later upgrade those to APs on the day we leave or we would lose our dining plan (ours was free, but he told us we'd lose free or paid if we did it before checkout day). There was LOTS of confusion about all of this, not as easy as most of the posted segments on this board would've made me think.
