Fishing Charters are expensive, but you SHOULD fish. The charter captain will put the bait on the hook for you and even cast for you. All you have to do is hold the pole and reel it in when a fish bites.
Fishing in Florida is FUN! I never thought I'd like fishing, but there are sooooo many neat fish in Florida. We like to pier fish. We have caught snook, jack crevalle, tarpon, grouper, catfish (OUCH!), mackerel, toadfish, porkfish, bluefish, and snapper right from the pier. Offshore, most people catch grouper, tarpon, dolphin fish, permit, and sailfish.
The gulf coast seems to have more of a variety of fish, but it will depend on what time of year you go.
