Welcome to the GunShine State.
1. Just wear a loose print or Hawiian shirt you'll fit right in.
2. Stay out of bars or the bar parts of places like Applebee's, etc. You can even have a beer with dinner if you desire, just don't be in the bar portion while armed. No flames, please, I'm just sayin'...
3. Disney doesn't like firearms...but it is not against the law. I carry when ever we go there. Just make sure it's concealed on your person, they search coolers and backpacks, but not 'persons'.
If discovered, they can only ask you to leave, be sure to do as asked. Keep in mind that signs in FL (you won't see many) mean nothing.
4. You can carry in churches, and you are not required to disclose to the cop who stops you on I-75 because you're trying to speed up the trip.

Out of courtesy, I would disclose. OMO
Enjoy your trip and spend lots of money down here...we need it!
