What time should you arrive for Saturday night showing? Would 7 pm be to late to get a spot?

Depends on what you are driving. Smaller cars usually can get in. I waz in an SUV and 7pm was when they cut it off.

This time if year the show isn't starting till close to 930 so you should be fine

There is lots of stuff to do there before the movie.

I definitely like to show up as early as possible, especially if it's opening weekend for a big release.
