This thread has become hilarious!!! I personally wouldn't let what anyone wears "ruin" my cruise, or cruise a different line for that purpose. A note to ducklite: Celebrity is quickly becoming a line with a lot of kids on board. I've cruised with them, without children, and they were EVERYWHERE. I also have many friends with children who also choose to cruise on Celebrity due to the great food they have. Also, when on Celebrity, there were all kind of dress during formal night, and those who weren't dressed approprietely, WERE NOT asked to leave the dining room, they ate like everyone else. By the way, I only saw a few people in tuxes on Celebrity, I actually saw more people in a Tux on our Wonder cruise!!!! A note on what my kids will wear on our Magic Cruise, DD 6 will probably wear one of her princess costumes and DS 3 will most likely wear a button down shirt and pants, since a tie at his age is RIDICLOUS!!! He actually has already worn a tux, when he was in my sisters wedding, but he'll be 3 and I don't think it's necessary!!!
