CNN totally blowing this one up. The passenger they are quoting is making it sound like none of the toilets are working and that there is sewage everywhere. It was one public toilet and one cabin that had toilet problems. It was a backup generator that failed in a test, and they aren't sailing the ship with passengers out of caution because of the backup not working. No issue with the main propulsion or electrical system, they could have sailed and no one would have been the wiser if nothing happened with the main system.
But at the same time, it is getting tiring hearing about Carnival having all these problems. Never seem to hear about a Royal Caribbean ship. Makes me wonder if Carnival is just a juicier target for the media, or if RCI ships really don't have these type of problems.
