Land at Nassau Airport (NAS), step onto a private boat, and be on Paradise Island in about 18 min. No ferry timetable, no overnight on the wrong island — the transfer is timed on your flight.
The public ferry runs on its own timetable and rarely matches an arriving flight; a missed connection means a night on New Providence instead of Paradise Island.
A private transfer leaves when you land, takes your luggage in one go, and covers the 14 km in about 18 min.
