All CM photographers walking around the parks are photopass people unless they are part of park media. Just talk to one and they can help you with your picture needs.
The meal picture package is like $32 or more and you cannot get copies of the pictures unless you pay that amount. Buzz Lightyear allows you to email someone a copy of any photo on display. The photographers you see in the park that are CMs are photopass and you can get the picture added to a card then use that to get your pictures. There is a photopass thread somewhere explaining how it works.
I just know the Buzz Lightyear one and not to let mom ever see them pictures as I ended up paying a lot of money for copies of two pictures, sigh, should have brought a cell phone to snap a picture of the pictures.
