While the ship is at CC, the kids activities are operated on CC. There is a sectioned off area just for the kids and there is plenty of shade there. They have sand digs and there's a water activity (not into the ocean, some sort of water spray thingy) to name a few. They can have lunch there with the kids in the club (they have their own shaded picnic area). You sign them in and out just like on the ship and the page system works as well (I know, we got a page after lunch) I'm not sure if any kids activities are held on the ship as well during the time the ship is docked, but once everyone is back onboard, that's when the activities start up again at the clubs. On the Wonder in June, the rehearsal for the kids show was scheduled as soon as we got back on.
