Here is a quote from the article:
"Crews will close sections of the park only during filming, and no area will be closed all day. Disney declined to say which parts would be closed. "We will be communicating that schedule to guests when they arrive on those days," Brown said."
I can't imagine them shutting down all of FL for 2 days. I could be wrong, but that just doesn't seem like something they would do. I would think it will be a major inconvenience, but would think you would get to see FL part of those days.
