Some clue about what kind of charter
you are talking about, what company you are talking about, would help.
In answer to the question, "Do you think yacht charters are worth it?" I would answer with a hearty "YES!" My wife and I charter
when we can and I can say--without any hesitation--that some of the very best vacations we have ever had were yacht charters.
But when I talk about our "yacht charters" I am talking about a very narrow band within a very broad industry. We bareboat
charter relatively small monohull
boats, and usually it is only the two of us on board (though, a couple of times, we have had a couple of friends or family
along). The term "yacht charters" can encompass anything from a 30' boat for a long weekend up to a luxury mega-yacht, with full crew, for a whole season in the Med.
My guess would be that what you are talking about is somewhere in between the two extremes. But that's just a guess. You need to provide more details before anyone can be sure that they are giving you a useful answer.
