We were discussing living outdoors -- and still get intellectual stimulus. (Preferably without people shooting at you, I assume.)

I don't know the subject, but a cruise ship seems like a more expensive variant of eating all meals at restaurants and going on a weekend trip every week? :-)

If you work for the cruise line, however, you get to live and eat on the boat for free.

Salaries are kind of low, but that is only because they know the perks (room/board/travel) make up for it.
