I can't answer you specifically, but I can tell you that every time we have rented a car in Florida we have rented it in one location and dropped it back at a different airport, and we have never had to pay an extra fee.
Like Bob P says they rarely charge a fee in FL because they have such large volume. BUT check before hand because it is not universal and varies by location. I've done it a few times on business never for personal use though.
