If it was just me, or just adults maybe we'd line up 30 min. before, but with our large group and lots of kids I highly doubt that will happen. We've been two years in a row and it really was not that crowded overall. Maybe took 10 min to get through the turnstiles.

I can't imagine it being drastically different this year. Hopefully they are selling the same number of tickets. One difference could be that we go on a Thursday evening. Maybe people line up earlier on the weekend?
