Not being a Floridian, native or otherwise, all I can say is this...
I have been to both parks several times over the years, with the kids. I will NOT step foot on Disney property ever again, because they are truly dicks about anything "security related". If their security types were actually able to handle a REAL emergency (I.e., an armed asshole/assholes), then I could see the point. But Disney security types are no different from any other unarmed "security"; with the exception of their attitudes.
I personally have never had an issue at either park (Disney or Universal); concealed is concealed. But I have witnessed several incidents, involving citizens who tried to be honest or just slipped up. Those Disney goons are quite confused... They think they are the real po-lice.
Anyway, an interesting discussion but a moot one, for me. HR 218 gives me no special exemption, so I take my chances like everybody else when I'm out of state. If I get made, I'll leave when told to. The trick is to be professional and not get made.
