Yes, as other's have mentioned Kid's Clubs are open when in port. And yes, some people are hesitant to leave their children there - I being one. My biggest issue is - we will get to our excursion and then we'll be "paged" b/c our daughter needs us. I'm not going to pay for an expensive excursion only to be called back. We chose to do things as a family, there will be plenty of time for us to do "adult excursions" when we cruise alone (one day)

Plus, this way she gets to see/do fun things in another country.
