Staying in St. Martin for a week, but have friends visiting ST. Barts at the same time. My wife and I are looking to take a 'day trip' to St. Barts. I know there' s a ferry, but i prefer to fly. Does anyone know the approximate cost to do so and are flights flown throughout the day? AND, is it possible to rent a car at the airport in St. Barts upon arrival? Thanks so much.
