I recently booked the Busan - Fukuoka ferry via aferry. It turns out that aferry doesn't actually do 'live' bookings for this route - all you do is submit a booking request, which presumably is processed manually. There is no real-time availability displayed.
2 days after submitting the request, I have still not received actual confirmation of the booking. As I can tell from the ferry operator's website, half of the ferries on the day I'm travelling on are already full, so I'm not very satisfied at the slow turnaround time on the booking.
