DH and I just got off our 9th Disney cruise on the Dream at the end of April and we love DCL. We don't have kids, but we both enjoy Disney in general. We just love the stateroom accomodations (having two seperate bathrooms and a tub-what a luxury), the attention to detail, the theming, the new Aqua Duck was a blast and the CM's onboard are the friendliest crew of any line we have sailed on. Course' the fact that you really don't have to pay to eat at different main dining room is also a plus. I get bored easily so it's all about the stuff for me.
Oh and Disney's private island Castaway Cay is beautiful and no locals to hassel you-it's all Disney CM's and you can charge everything back to the ship using your KTTW Card. Did I also mention that soda is free????
It's definitly our favorite cruiseline.
