Carnivals Magic August 2017 Southern Caribbean cruise is monitoring bad behavior as a prototype for future trips.  The memo reads:  Thank you for sailing on our fun ships.  Please note.  If you bring snot nosed, passageway running, adult pool hogging, hot tub snorkeling, pool peeing, pool puking, elevator riding, screaming, crying, chair hogging, MDR food throwing, rude, obnoxious brats or 20 year olds you will be disciplined and if the behaviour continues possibly removed from the ship at the cost of the traveller.  The memo continues but you get the message.   I think it's great seeing how I will be on that trip.Happy
