Last season I went to PKI opening day to get my picture taken for my pass- I already took care of payment online. I was there a little past 8AM. I was about the 10th person back in line to enter the season pass booth for my picture. This was before they moved picture taking to The Paramount Theatre which I believe was only a temporary early-season practice. They opened the booth a little past 9AM and I was done by 9:10AM at the absolute latest. It was a relatively fast and painless process. Stand up against the wall, look at the guy, friend makes me laugh, end up with a horrible ID pic. :) I would suggest you get there around 8-8:15AM. Keep in mind that the parking lot doesn't open until 8AM so I would figure that into your drive time to the park. By 8:30AM, the line was stretching back pretty far. I was able to enjoy the rest of the ERT that day.
