Very simply, cruise ships pack a lot of people together in a small space, just as occurs at a stadium or nightclub, etc. Very simply, I don't like crowds. I prefer to face challenges where at least I have room to maneuver.
Of course, creating a crowd and putting it on the water does generate some unique problems.
+1 on that one. If I cannot bug out on my own two feet...
And yeah I'm the guy who always has a torch on him.
