Photopass info please
 

What is photo pass? Should I purchase it? Would I purchase it over the web before I leave for Disney or while I'm there?

If you think you're going to get a lot of pictures taken, definitely pre-order it before you go to save money. (There's a link for the pre-purchase offer on the page linked above.)
