fwiw

while I've only been on one Disney Cruise and generally agree with your comments (see my post below, other than our pool cleanliness), we have been on many, many Royal Caribbean cruises and I'd say for Voyager, Freedom and Oasis classes of ships, the cleanliness and onboard ship quality have been very, very good.

I was on one of the initial two Disney ships (materially smaller than any of the RCCL classes of ship I mentioned) and the Royal Promenade blows away anything on those Disney ships.

The bottom line is if you have kids the "right" age and your family enjoys Disney, that trumps all else and people should take the Disney cruise. If your kids are, say 15 or older, probably better off on RCCL or comparable.
