My friend I am not talking fires only. but lets look..........the Splendor and Triumph came with in a air breath of going wild. Hell the Splendor didn't even have the right manuals to operate the suppression systems. I was in Miami when the Ecstasy burned the passengers were watching the stern of their ship burning on the news and the Captain was telling the USCG (who was watching the fire), saying his ship
was not burning.
Don't forget legend and Dream engine breakdowns that required the passengers to leave and or the ships limp home.
My understanding the Liberty has had past problems as well. Now it seems she had a severe engine fire.
Don't forget the Tropicana.
Now the other issues, the faulty design of some of their ships. the entire Destiny class having major mechanical issues, many ships had no redundancy in safety systems, many of which are slowly being added in the yards...........add the Costa Millimimun fire that sent her to the scrap yard.
There are repeated reports of the Carnival vessels built for Carnival line at Fincantieri have electrical problems.
and lets not forget the Costa Concordia....33 lives lost..........all because of the playboy captain and the office staff who delayed action trying to protect Carnival Inc. 5 have been given prison sentences.
And that is all I can remember on the top of my mind
Yes, RCCL, but to my knowledge those were all minor and the Grandeur was a cigarette fire , by a passenger that threw it over the stern and it blew back onto the aft deck. The enchantment was due to a light bulb burning a life preserver. the Majesty and allure were minor engine room fire and they continued on the voyages.
Disney has had 2 minor fires, 1 was a closet fire and the other on the Magic was a insulation smoky fire in the aft stack. The insulation over heated and never did more the spark with minor fire and distort the thin sheet metal outer shell and then she was on her way.
Seems to me there really is no comparisons......the magnitude of the incidents on Carnival highly out weights all the others.

@Tonka's Skipper I am not in anyway defending Carnival. If I were, I would have omitted the location of the fires for both them to mask where.
It was just a count, and obviously does not take into account the severity of the damage caused or whether the vessel was able to recover and continue sailing. I also only looked at the past 20 years as that was the closest I could within the time frame Disney have been operating.
I personally think Carnival have been very slow to upgrade their vessels after a fault in there design is found, and PR is probably the main reason they have done so. They appear to be more reactive than proactive, and slow at that. Also they could do with an imagineer to at least mask the back up ten set's in some way

With regards to the design of there ships, I heard about the class certification? and insurers. Why would they sign off a vessel with obvious design faults? Why did the USCG not pick up that the wrong manual was on the ship, and they crew did not know how to operate the fire suppression system? I would have thought that would be something they would want to see demonstrated (obviously not to full operation of the system)?
The Magic and Wonder were built at Fincantieri also, and have also had electrical failures that have left them at sea, without power, until they could restart or fix the problem? I've not read about the closet fire, only the stack fire that melted the funnel outer shell and burnt the stacks down. I've seen the photos on CC, and that cannot just be sparks and insulation! They also had a fire on the Aft deck near the buffet when a firework did not launch properly according to cruisejunkie.com.
As @ilovetexas said, Carnival seem to have more engine room fires than other lines, but a fire is a fire. Why are they certified to sail if they are so prone to mishaps and poor design?
