what day of the week do they have a movie showing during the summer?

Saturdays at 8pm. I think I posted on Google guide the list of the movies. The next movie is Daddy's Home 2 and the following movie is Deep. Look at post board in front of the gym, it's posted there. It's fun, me and my kids watched The Emoji Movie last Saturday.

Sorry but you would have to call the park for that information.
