Here's what I understood from our Photo Pass experience this past week.
Let's say you are at MK. You have several pictures taken there. You can view them there, or wait till you get home. You can not go to EPCOT and see your MK pictures.
Take the card with you to one of the other parks, let's say EPCOT. You get more pictures . . . same Photo Pass card you used at MK, but again, you can only view your pictures taken of you at EPCOT in EPCOT.
You can go home and, within 30 days, you can actually see
all of the pictures you took at all of the parks on that one card.
I believe I had one guy tell me that you can only get the pictures once you get home. I don't believe you can have the special borders and WDW icons on your pictures, or Tinkerbell flying by your head on the ones you order from home. You can only get those if you order them while at the parks.
We ordered ours from each park. It really is a pain to have to only go to that particular park. We were at MK and, after thinking about it, wanted more pictures from EPCOT. So guess where we had to go? Yep, back to EPCOT, just for those pictures.
But that's o.k. The Photo Pass people were very fun and helpful.
