Thanksgiving week will HAVE LOTS of kids. It is a school break period. Any time that school is out is going to have more kids than not. I have never seen a cruise on Carnival with NO kids, but I have also never sailed during a non school break period. I have noticed that even though there may be a lot of childern on the ship, it never seemed like it. But I'm also sure there are people with opposite experiences.
