A NEW COURSE
Cruise lines once might have been known as floating bar-buffets that provided just a few activities for kids as an afterthought. But now almost all cruise lines -- not just pricey Disney cruises -- offer ships that balance entertainment for adults with activities for kids. From multistory waterslides and rock-climbing walls to interactive Nickelodeon shows, these ships offer some of the best value for families with young children. The per-person price ranges listed here are based on weeklong Caribbean itineraries, except where noted.
