One should ask the pod cast speaker why he is a former employee of a cruise ship? Perhaps, the money is better on land?  Or, perhaps he couldn't handle the stress of working with difficult people?

I've worked in ski resorts when I was considerably younger, and yes, it was fun for a young, single.  But, the public can be very demanding, and having the right temperament is important.

I should think it depends on the amount of money you have stashed away, as well as your skills with languages, and educational level.  Not everyone speaks English, although most do at least on the ships on which we traveled.
