Not to add fuel to this topic, but I recently did a search on reported cruise ship fires and did note the vast majority of them are related to Carnival. Now I completely understand that Carnival does have more ships in their fleet than other lines, but the percentage I reviewed just seemed high. The last cruise ship fire that really made the media was also Carnival in the late 90's off the coast of FL when the laundry room went up. Hopefully the line is learning from these past errors to increase preventative measures, but the number of fires per ship does appear to be Carnival by the largest percentage.
