Well, except when I was there (at OBB in September). they were no longer doing that lineup thing...I was basically told there were now "roaming" photogs in each land and if you saw one, just ask them to do a shoot. I did see a young woman with a photog on the side of the castle by Royal Hall. Her boyfriend was holding her purse while she was posing and the photog shot several poses and then they moved to another location.

. I wanted to do it cuz
@DizMe's pics turned out so cute...but I just felt weird about asking random PP people, "hey can you shoot pics of me?" Just not in my DNA.
I'm sure it's completely random and to be honest, I never saw another photog just standing around in a random location, waiting to be approached.
Good luck!
