I’m glad that nobody was injured. Despite the drills, evacuations of cruise ships tend to be chaotic. The problems only increase with the number of passengers, which is why smaller ships are gaining in popularity. Passengers cannot always count on the crew*, either.
Also, if the cruise continues after a fire, the experience can be terrible. Having independent trip and health insurance is always a good idea:
