Fishing in Key West is a lot of fun, but it certainly isn't cheap. Private charters, which charge approximately $600 per group for a half-day tour (excluding gratuities), may not be ideal for families with young children. Gulfstream Fishing has the solution with a six-hour deep sea excursion at prices of $65 for adults and $38 for children under 12. Best of all the wee ones (under five) are free. This includes parking, bait and license; add $5 for rod rental. Their 58-foot Gulfstream IV party boat comes equipped with an air-conditioned cabin, restrooms and snack bar. Anglers can haul in grouper, snapper, mackerel, kingfish, tuna and sharks. The mates will become your best friends, as they help you bait your hook, gaff your catch and clean your fish. (Don't forget to tip.) Head straight to a local restaurant and have it cooked up for dinner.
