Le Boreal is not especially aimed at families but does carry children and makes them welcome. There's no structured kids entertainment or activities; French families tend to do everything together, including eating dinner, and all the children on my cruise seemed sophisticated and well-behaved. Kids menus are available on request, but there was plenty on the buffet or menu in any case that would appeal to kids -- pasta and omelets, for example, and ice cream every day. The waiters were generally very sweet with the children. A small children's playroom was unsupervised but had a good stock of games and toys, and we often noticed small children playing quietly in there. In the Karikal Lounge, a giant screen with Wii kept the teens amused. In-cabin baby-sitting is sometimes available on request, especially on family theme cruises, but you'll need to make arrangements with the Hotel or Cruise Director on a case-by-case basis.
