If the rule is that seats cannot be saved and some have roped off large or even small areas then the easy solution is to take the ropes down. If one of those saving seats confronts you they should be reminded that (a) you will file assualt charges, (b) if assualted or even threatened with assualt by someone who has the ability to preform an assult, (e.g. forms fist and aims at you, etc) then the assualt may be rated a "higher assualt" for threatening a person over 65 in Florida. Also, you will pursue the charge in court and they will be fined and maybe sent to jail. Are the seats worth it to them? And if they go on then file the charges, (get witnesses at the site).
