Some CMs will start the process before the turnstiles open, but not all. The ones that do step outside their gate and go down the line checking everyone's passes to see if they have parkhoppers and if they have their picture in the system. If someone's picture wasn't in the system, they would take the picture right there while waiting in line. But even if the CM in your line doesn't do that, the PPs are right, it barely takes time for them to snap the picture. On your first day they also give you a sharpie to write your name on the back of your pass.
