We let our AP's expire as we knew we wouldn't get a chance to go to WDW to make it worth our while last year. This year we are going 3/31-4/7 with a 6 day Park hopper (me, DH and DSx2). IF I decide to upgrade these tickets to AP's, can anyone tell me if the AP date starts the day I upgrade OR the day I first used the 6 day PH? If it's the day I upgrade, it probably makes more sense to wait until the last day we are there unless I want a TiW card for this trip. Thoughts? Thanks!
