I haven't rented a Florida car in a long time, but I used to be in the travel industry. The airports are aware of the technique of travelers picking up a car from a non-airport location to avoid the HUGE fees the local airport authorities or CVB authorities impose on car rentals. In some cases, if you are an out-of-state renter, even if you pick up the car from, let's say, a downtown location, they will STILL hit you with the airport fees. Unfair? Of course it is. I'd be interested to hear people's recent experiences with this.
