LU, every year the news has updates about some cruise ship with a norovirus outbreak. Stories of employees getting it and puking in the sink. Then later they use that sink to prepare food.
Hundreds of people now have it. They are quarantined in their rooms for the entire cruise. Miserable. Later when they get off the ship they have quotes about how they missed the best fun stuff and all they got was a voucher from the cruise ship for another time.
That said… I have a friend who loves cruises. I told her that I’m scared of getting sick (and being helpless and trapped in a tiny room at sea). She said that it’s so much fun and not to think about it.
