When you're young and on holiday it tends to be all about getting drunk and pulling. However, on a cruise the rules are completely different. Stick to these 5 tips and I'm sure you won't embarrass yourself.
1) Drink before noon
2) Take alcohol or illegal substances on-board with you
3) Forget your room number
4) Be late for departure
5) Always cover up when not in the pool - going for a meal in a bikini is not appropriate.
