That is totally ridiculous. I can't even believe they would ask you to do that, for the sake of a cruise, no less. One of the most ridiculous in-law stories I've heard yet, and there are a lot of them on this forum.
I don't know much about induction, but I always want to let nature take its course unless something is actually medically wrong. I haven't done much research on it, but from what I understand induction can make the contractions more intense (and painful!) and sometimes lead to complications. I would research it fully before deciding, so at least you have some medical facts to give them, besides just telling them off. But I'd be sorely tempted to just tell them off!
