I've heard many people say that Carnival ships are, just as it sound, a party ship, due to being lower cost. That they attract a younger crowd, you see more drunks, unruly behavior etc.
Is that generally true?
I've only been on a cruise once way back in 2004, the Sapphire Princess on its maiden voyage, and that was outstanding, with everyone well behaved and orderly,, but that shows the extent of what I know about what to look for in a ship.
