The only time I've seen one of the screen rooms used long term was on a manual roll out type awning and like when I kept our awning out for weeks at a time, the guy was using additional hold down straps. One from end to end over the ends of the awning, arms attached to the ground with additional straps on those arms using ground screws and/or 12" nails stakes for both arms and rachet tie down straps. He also used long tubes filled with water to hold down the screens down to the ground. Still saw the screens blow loose during bad "hair" days.
Best of luck with what ever you decide.
