I'm in a group doing the Carnival Legend Norwegian cruise next year and a few in the group wish to debark in LeHarve. Might as well since it's the final port of the cruise and they will get a jump start on the continent. I was told there is a shuttle from the pier to the train station (5-Euros) and from there connections to Paris. That should be good for day trippers or those debarking. I'm sure the day trippers need to be on the early trains if they are brave enough to do that!
