your stuck in a port town

I said you're basically limited to coastline and port cities to point out the contrast to other modes of travel that aren't nearly as restricted. You either missed that point, or you're being pedantic.

there's nothing to do out at sea

My point was that without cruise ships, there would be nothing to do out at sea. Cruise ships solve the problem of "there's nothing to do or at sea", but in an unnecessary and dumb way, in my opinion. So again, I think you missed the point of what I was trying to say.

Ultimately I don't really care what anyone's opinion on cruises are. What I do care about is making sure I'm understood correctly, hopefully this helps.
