My little one woke up early every morning and we would wander around the ship until everyone woke up. A couple of mornings I took him in the Cove and got a cup of coffee. I just explained to him that it was an adult's-only place and he would have to be still and quiet. He usually sat on the steps at the door. Nobody said a thing about him being there. He loved it in there and would have loved to be able to sit and have a hot chocolate or steamed milk and just hang out like the grownups. I think it is okay if they go in there with you if they are behaved and don't run amok!
