My husband and I have booked a balcony room and we have a 4 year old boy and 7 year old girl. My husband is afraid that our boy will some how get past us while we are sleeping, open the door to the balcony and fall off....Since this is our first cruise, does anyone know what type of locks are on the balcony doors? Is there plexy glass on the balcony railment or ???? Any information is great! THANKS...PS..>We are sailing on the Carnival Victory ship. THANKS again!
