We were just there for 5 nights 2 weeks ago. I had e-mailed them in advance, and asked what nights they would be shown, and was told either Thurs or Friday (I don't remember which, just one night that we weren't going to be there). But, while we were there they actually had 2 dive-in movies: Robots and SPy Kids2. I think they were in place of other events (live band etc) that didn't show up. I think it's hit or miss. They have a schedule of activities, but we found that it was almost never followed for one reason or another.
