Children are not allowed to stay in the casino. There are activities aboard the ship geared toward children. The casino is not a place for children and probably someone, including me, would complain. Unlike Luv2cruise, I have not seen children in the casino (Celebrity) except passing through with their parents/guardians. On one cruise we did see small children running back and forth through the casino..casino management stopped that quickly. Agree with it or not, please do not forget that the casino is an adult entertainment area and a lot of adults do not want to share that area with children. I am one of those adults. I am sure that your son is probably very mature for his age and would not create a problem in the casino...BUT...where does it end? There has to be a standard set and the cruise lines have set an age limit for the casinos.
