Thanks for the clarification.  Either WKRG or Carnival got their stories wrong.  It just didn’t make sense that the entire ship would have been evacuated.  Sorry about missing a stop - that’s the down side of cruises.  Their small print says they reserve the right to give you a miserly amount if they have to cut out a stop or change the itinerary.

The only logical reason is that this person somehow posed a threat to all passengers and it is doubtful that a purely physical illness could have been involved.  Could it have been someone making threats that endangered the ship and all the passengers, so they had to evacuate the ship to assure the threat was not real?  It’d be easy for Carnival to classify this as a “medical” emergency, when it may have been more “mental” in nature, and given Carnival a way to cover over an incident that would alarm others and reduce future bookings....TV5 should have pressed Carnival on this possibility instead of parroting Carnival’s very vague, and frankly illogical, explanation.
