I actually just did it this past Sat and got there at 8am and though I was going for the matinee, the 8pm front rows were already gone by my turn. I got the 3rd pair for matinee (of 10 seats).
Though, there was a whole family that lined up EARLY (6am?) to make sure they got 6 for the evening so they took 3/5ths of the 8pm right away.
