How young is too young?

[Minnie&Mickey]

I am thinking of booking a trip on the Disney Dream for June 2012. I have a lot of DVC points that I will need to use or lose, and I know my family would love to go on a cruise again. My oldest daughter and her husband have a baby, and he will have just turned two by then. I know there will be a lot of different opinions on this, but is he too young for a Disney Cruise? I don't care that he won't remember it, we will have plenty of other opportunities for that, but will it be too hard to deal with a child that age on a cruise?
