I stayed a bit north of there years ago, in Crystal River, FL. We went out in a little 18 ft skiff each day, and fished the flats for anything that would bite. Caught lots of speckled trout and redfish. We even went out a little ways, dropped anchor, and chummed for sharks - caught several blacktips, various small sharks, a few large stingrays, and some spanish mackerel.
If it were me, I'd be looking for a place to rent a little 18 ft skiff or so and see what I could go out and catch. That would be an adventure in itself.
