What time do you have to get there to avoid a line to get in and to guarantee you get in

Depends on the dsy and what's playing. Weekdays 7pm us usually clear, Fri-Sun i recommend no later than 6pm

We usually get there by 6pm on weekends. They open at 7 or 7:30, depending on the line of cars.

And you might go when the they say open to let you in and just hang out til the first movie starts.

About 7pm

There's usually always a line started by 530, but it's not terrible. When we go, it's 6ish when we arrive & are normally 10-15 cars from the gate
