I’m going to guess it’s the people that leave them up when not in their cabin. We had “hooks” on the one connected end and we unhooked them, and rolled them tightly and tied them away in the corner of the balcony. Again, these were VERY lightweight parachute type material that folding them up for storage they were so compact that they nearly fit in a jacket pocket. I do understand the “escape” and safety hazard, and it’s too bad people can’t see why they should be stored away when not in the cabin. It was so amazing being able to relax on them instead of the uncomfortable chairs and therefore I will be bummed if they truly won’t allow them any longer after using them on so many cruises without issue. But I understand the reasons and rules.
