Sure, plenty of cruise ships cater to families as their primary audience — but less obvious choices, including river and expedition ships, have major perks for people traveling with children, too. While these ships don’t have water parks, character breakfasts, and kid-friendly musicals, they do have awesome programs designed to keep young cruisers entertained at sea and on land, many that involve the whole family. One caveat: While some of these ships welcome children year-round, others offer special family-friendly programs during the summer and holiday breaks.
