From Vladivostok it was a 16 hour ferry ride to South Korea. Great cabin for 8 all to myself. Confusing since there were only 6 bunks. Then I realised that the open wooden area was for 4 others to kip on the floor. Confirmed at the first hotel where I had to sleep on the floor. Not that comfortable but it means all of the beds here are nice and firm and not those wimpy jelly like matresses.
