I wouldn't go out of my way to book an "adults only" cruise. I'm more concerned with cost and itinerary and a particular cruise line. The only time we were ever really bothered by children was a 3 nighter to the Bahamas during spring break- very bad planning on my part! We were all kids once, just as we'll all be old one day-live and let live I say. There really aren't many bad kids out there-just irresponsible,overly indulgent parents.
