Holland America's Club HAL is offered to children 5-12 and teens 13-17 aboard the Rotterdam. There's a full-time youth counselor, but the level of activities really depends on the itinerary and time of year (e.g., school breaks). However, potential passengers should be aware that the ship is not particularly family-intensive by any stretch of the imagination (though most children will surely enjoy themselves). Babysitters are typically easy to arrange.
