When do people start typically lining up to get in?

Depends on how popular the movies are and what day of the week you are going

Hard to say. Some go a hour or so before the movie. To get a good spot you can let the kids play on the playground at times people are there set up to sell different item's. Some people are still arriving when the movie starts kinda annoying but it is what it is.

7pm... Sometimes 6-6:30pm if its a popular movie.
