We had an 8:15 show and lined up around 7:30. There was already a long line, but we ended up in the 7th row I think. By 7:50, I couldn't even see where the line ended. But seating is guaranteed, so you will get a seat if you have the package. The closer to the front you want to be, the earlier you need to line up. And people will start lining up for the CP while the previous show is still going on, which makes no sense to me.
