Someone on another board has a good idea for the cruise lines----since the cruise lines find it too hard to enforce their own rules, they should do away with any rules period. Also do away with the dining rooms. Look at the money they would save on waitstaff, china, nice tables, etc. Just have one large room with a bar, pizza place, cafeteria, etc. and let people come and go at will dressed as they wish. No rules, no nothing but some food and drink. No doubt they would never sail less than full.
