HOLLAND AMERICA

This is a cruise line that actually had a ship rescue tourists who were stranded in 2012, so it makes sense that they would consistently be ranked as one of the most ethical companies out there. They even have a policy that requires doctors on their ships to be licensed to practice medicine in North America, which is rare. All of which makes it odd that one of their ships recently failed a health inspection (something that almost never happens) & that they actually have the most reported cases of norovirus out of all cruise lines over the past decade.
