We boarded three separate cruise ships! Check-in is (presumably) up to 30 minutes before departure, and the meeting time at the boarding area is 10 minutes before, but there are food stalls and tables inside the check-in building, so waiting there would be good to avoid the cold! Japanese guests are grouped together and accompanied by staff who can speak Japanese! We took an evening cruise and it was cold, but warm drinks and blankets were provided for us to use freely. They launched fireworks from a spot where Gwangandaegyo Bridge was visible, and took photos for us with our own smartphones and cameras!
