We have been there for February and November times in the past couple of years. We were there at rope drop each time, and were within the first 15 - 20 kids signing up. By the time we were walking out of sign-ups after 15 - 20 minutes or so, they were beginning to turn people away who were not already in line. It literally fills up within the first 30 minutes of park opening, or at least it did on our four trips.
