I know I'm going to draw the wrath of a lot of people (Including Priscilla) but I don't think children belong on a Celebrity cruise. Celebrity is a more "adult" cruise line. There may be a kids club onboard, but there are no slides, no splash zone, no go carts, no roller coasters, no carousels, etc. Maybe you should take your kids on a Royal, Norwegian, or Carnival cruise. They'll have a much better time. Just something to think about.
