Accidentally exposing or printing has been fixed in the law but some police will still give you a hard time for it.
You won't have any trouble with it in your vehicle. With your ccl you don't need to keep it secured.
I carry all the time in florida, not to much in south Florida but I have never had a problem. Also Florida does not have a duty to inform law so unless a cop asks you don't say anything. Just do your best to conceal and try not to print folks in south Florida might panic lol. Hope you enjoy your visit and stay safe.
