In the past decades, Norwegian cruises have seen more than 30 outbreaks of norovirus. The line also does not employ lifeguards on its ships, leading to preventable drowning injuries and deaths.
Carnival is one of the most famous cruise lines in the world, but that does not equate to having a stellar record of safety. In 2016, the CDC found severe mismanagement of one ship’s drinking water supply and other unsanitary conditions.
Disney is one of the most recognizable brands on the planet, and stakes its reputation on being friendly to children. Nevertheless, there have been cases of serious safety violations onboard Disney cruise ships.
Royal Caribbean, another popular cruise line, has had issues with ships embarking during major storms, leading to passengers being injured. It has also seen fatal accidents during off-ship excursions.
With only a few ships in operation, Margaritaville at Sea has still seen plenty of safety and sanitation issues, including overboard incidents, fires, and failed sanitation screenings.
While Seabourn is known for its luxury cruise vessels, it's also experienced its fair share of accidents and issues, with a history of both a norovirus outbreak and a collision.
