I loved the Disney cruise but, I would wait until the kid was 3, because you have to pay extra for 2 and younger in babysitting. The pools were ok on Disney, it was my 3 cruise and I have never been that impressed with any cruise pools. There was only a splash area for kids still in diapers. Would I go on a Disney cruise again, yes but it would have to be a great deal. There is alot for the kids, but not alot for the adults. That is why I booked my next cruise with Carnival. As I understand it, Carnival has a good Camp Carnival and adult activties.
Hope that helps.
