Are the itineraries similar? And has everyone in your party cruised before? This question ( with slight differences ) gets asked a lot, and I think it depends on what you are looking for.
For example, my youngest is autistic, and while we can do a short vacation ( 2 or 3 nights usually ) he can't handle anything over that. We booked Disney since a 3 night on any other line can be considered a "booze cruise". I know not every one is like that, but we didn't want to take the chance.
But if the itineraries are similar, how important are the extra nights on board? How about the night life/adult entertainment? I know all of the major ships have kids clubs now, but how do the youngest ones feel? Do they LOVE Disney, or would they be just as happy on another line?
Just my thought process if it was my family. I hope that points you in the right direction. And coming from someone who has not cruised before (we have a cruise booked for May) there is some great and not so good on every cruise line ( Including Disney) so I don't think you can really go wrong with any of your options.
HAPPY CRUISE PLANNING!
