This woman missed the boat literally. She was about 40 mins late, maybe more and the ship was pulling out as she was hurrying to the dock. Her hubby got off to look for her and left their kids on board with his brother to look after them. He took his and his wifes travel docs and apparently NCL was aware of this and they flew back to NYC with some help form NCL or so I read.
