I would expect a good number of kids on board for this cruise. Regent should put on a staff member if there are more than 10-12 younger kids (nothing your 16 would be interest in) to assist (not babysit). The vast majority of people have absolutely no issue with kids and neither does Regent. If your kids are well behaved there will be no issues at all. In fact, it has been my experience that kids are better behaved than adults. You will have a wonderful time!!!
