I avoid this place like the plague. So glad I only need to come every 4 years.
Photo center is in a separate building from everything else. A huge room with dozens of chairs lined up,usually filled with miserable,impatient and/or totally aloof people, almost always texting or taking photos of themselves while they wait their turn.
Aside from that, you pull a number and wait for them to call it. I think I was out in about 30 minutes or so, but still, I wouldn't be back here before I need to be!
