We have done 14 cruises (
RCCL, Carnival, NCL & Princess), and none with Disney. We are DVC members so I don't even think of Disney as a "cruise vacation".
It was nice to see Disney is most like RCCL, which is my favorite cruise line.
Since we don't have children, I am always afraid that the Disney ships will be over run will children running everywhere. I have been told this is not true, but have not been brave enough to spend a week held captive on a floating resort with no way out.
Maybe some day we will try it.
