Actually, I was caught one week by the port security guards. They were like "hey...you're here every week!" They made me a deal. If they let me onboard, then I would have to steal food from the buffets for them and their families. So, every week, I'd show up with an empty backpack, they'd let me on whatever ship was in and then, a few hours later I'd come back with a backpack full of food for them. I did that for about a year! Nobody on the ship ever stopped me for anything. I actually had a crew member on the Sun Viking let me into crew areas and show me around!
