During weekdays just before dusk is fine. Weekends 7 ish is good. Make sure bring bug spray.
6:30 to 7:30 is plenty of time ahead of the first movie @ 9:30.
Get there early for a good spot!
We usually go at 630 have never tried to get in after that
Its usually sundown or at 11 when they let you in so you don't disturb other movie goers. That's just my experience though
