Jack Doebbler walks to his vehicle after getting off the Caribbean Princess cruise ship, Friday, Jan. 31, 2014, in La Porte, Texas. The ship returned to port early on Friday due to a dense fog advisory and not because people were vomiting and had diarrhea, a Princess Cruises spokeswoman said Friday. But passengers said the crew announced on the second day of the cruise that people were sick, apparently with highly contagious norovirus, and that extra precautions were being taken to ensure it didn't spread.
