I don't know KY law, but Florida CC law is pretty simple...
You do want to read the info on the resource page that will give you the few places you cannot carry.
Concealed carry with a permit is OK nearly everywhere (except the list) and open carry is illegal everywhere (except for some hunting/fishing exemptions).
YOU CAN CARRY IN RESTAURANTS! YOU CAN CARRY AND DRINK (just not be drunk, about the same restriction as driving). You CANNOT carry in a bar that is only a bar, or the bar room of a restaurant. Simple test, if you can smoke, you cannot carry as smoking is allowed in stand alone bars but not in restaurants.
Other than those places on the list, no carry signage etc DOES NOT carry the weight of law, and you will find very little of it. If you are going to Orlando, carry is privately restricted in the theme parks but again does not carry the weight of law, but I do not recommend carrying there because of safety (see my multiple other posts).
You may also have a LOADED AND ACCESSABE firearm in your car WITHOUT a permit provided it is inside the glove compartment or other closed area or in an enclosed case. In my case I have a permit but my wife does not but when we travel in the state, I leave a weapon in the glove box when she has the car just in case.
Florida is a Castle Doctrine state and has no duty to retreat rule and is fairly liberal on its definition of acceptable "use of deadly force" and exempts self-defense from both criminal and civil proscecution.
Welcome to the forum and to our great state and have fun!
