We got a notice on our door while on the Fantasy last year that a child who was at the Oceaneers Club the same time as our daughter was found to have head lice. We checked and checked but our daughter never got anything. As others mentioned, it's highly unlikely to get them from a bed. They usually transfer from person to person and they can jump so it could be your daughter was playing or in close enough proximity to a child in the club who had them. Even if that is where they came from, the lice don't infest the club. They live on the on the people who had infestations there so unless a CM on the Magic who also has them, the lice left the ship when the infested kids left. I wouldn't be concerned at all about cruising on the Magic tomorrow. Just teach your kids to keep their hair away from others (no hugging), not to share hats, hairbrushes or dress up clothes. And now I'm itching too.
