I've cruised mostly on Celebrity in the past. They usually tell passengers that they must be back on board one hour before leaving a port. I noticed that NCL, specifically the Prima, says we must be back aboard two hours before leaving a port.
How strict is NCL about this? If I get back to the ship one hour before the ship is due to leave, will that be a problem for me? Of do they say that just to make sure the last minute people get back in time?
