We are going on the NCL Start out of Reykjavik. It is scheduled to depart at 6pm. So I believe we need to be on board by 4pm. Our plan is to do an abbreviated Golden Circle that day, so targeting to be on board by 3PM. Today check-in opened and the latest time slot was 1:30 - 2:00. I do not think we will have an issue, but thought I'd see if any others have boarded past the latest 'check in' slot available recently to make sure.
