RSVP for plus 1 but not invited that way

Why do people just assume everyone is invited to a wedding and not specifically the names on the invitation?  We had decided early on that single friends would all be invited "and guest" since there were only a few and we figured they be more comfortable taking a vacation with someone.  But kids are becoming an issue.  We are not having an adults only wedding but I thought the only children would those of relatives.  I made it a point to state that babysitting services are available at the hotel thinking that people would bring their kids on the vacation but not the actual ceremony/reception.  Now we've had at least 2 families say they are bringing the kids.  My fiance doesn't want to say no but of course it we say yes to these, we have to say yes for others.  Besides the added expense if there are that many kids, we now have to think about "entertaining"them at the reception.  UGH!

Some people simply do not like taking vacations without their kids. And although babysitting services are available, this isn't always going to be a comfortable option for a lot parents...it's a lot different trusting total strangers in a different country to care for your kids, then a regulated childcare professional in your home state/province or the babysitter down the street you know quite well. Therefore, unless you specified in the invite, "adult only" ceremony/reception, I think you just need to accept that people will bring their kids. And I wouldn't worry about entertaining the kids at the reception...that's their parents problem, not yours!
