Disney is made for kids....I can't imagine any other cruise line being comparable for families, especially with younger kids.
Let's face it...Carnival wasn't originally meant for families...what they did was start to market themselves as family friendly and toss in a Camp Carnival.....I haven't ever been on a Disney Cruise, but if you put the Disney name on something, you know it's going to be good for your kids because Disney is all about the kids...Carnival is not.
Comparing the two lines doesn't even come close to making any sense.
