Not sure about Port Orleans, but they do it at Contemporary/BLT. We watched Beauty and the Beast back in Nov/Dec. Didn’t plan on it and just stumbled upon it as we were headed to our room. Dropped off our stuff, stopped and got some snacks and laid in lawn chairs near the pool. By the time the movie was over, all the lawn chairs were filled and people had blankets and towels sprawled all over watching the movie. Something we had never done before and loved it.
