On cruise reviews there’s always a spot for “children programs.” I’ve never paid attention, but if I’m not bothered by kids on a given cruise I just assume the programs (or parents) were up to it. Never cared much for misbehaving kids – or yappy little dogs for that matter.
Since I am a former teacher, I actually love talking to kids on cruises. If they are misbehaving I don't hesitate to talk to them quietly about their behavior - even if their parents are nearby and ignoring their misbehavior. I also usually make it a point to check out the kids camp facilities. That is the only time that you can get into them unless you have a child with you. .
