I work in production. The business is changing faster than anyone can conceive of. I think its really important to be able to provide content now. I would take the gig and find a way to put your other skills to use on the trip. Suggest something, pitch an idea that can work on the cruise, this way if you can get something off the ground you can note on your resume the job you were hired for and whatever it is you created.
Make the pitch professional looking, and back it up with good quality facts, even if they don't go for it people in the business really respond to innovative thinkers.
If your idea makes money and the company who hired you are pleased thats one bonus point, but believe me when its on your resume people will want to know what and how you did which is another big bonus point.
Usually in a fast evolving environment like TV, innovation presented correctly is very very well received especially if they think money can be made. TV will become far more about event creation, and specific demand.

So you can't spend all your off hours looking at the chicks by the pool but I think you could make this opportunity a resume builder.
