Hi Twinglemum ~ We just got back from a trip in February and it was the first time we used Photopass. The park photographers that take pictures around the park use the card to store your information. When you see a park photographer on your first day just ask them for a Photopass card. There is no cost to have the card. Then each time you see a park photographer and you would like them to take your picture just tell them you have Photopass and they will swipe your card and store your information with the photo. You can still go at the end of the day and check your photos and purchase them or you can wait until you get home and look at the photos on-line and purchase them then. I am not sure of all the prices but the 5x7 is $12.95 (if you use the Disney Visa you can get 20% off your order with a code). I also just received an e-mail from Photopass for 30% off my order. It is probably a good idea to check your photos before you leave the park even if you want to buy them when you get home. I really wanted a picture of me and DD holding Tink at MK but when I got home DD and I were just holding out our empty hands. We also had pictures missing from AK. I liked the idea because I usually avoid the park photographers because I don't want to stand in line at the end of the day behind 50 other people to look at the pictures and with Photopass I have the option of buying them at home so I don't miss out on any great pictures.
