We want to have an adults only reception for multiple reasons, but what is the age cut-off for a "child"? I have a fifteen and a seventeen year old cousin that are very close to my family and I wouldn't think of excluding, but does that mean that I have to include everyone's kids? Including the other cousins that aren't as close? (I have 16 first cousins and most have kids themselves) If everyone brings their kids, there'll be at least 20 of them! Also, most of our guests will be coming from out of town, so what will they do with their kids? Should I try to coordinate babysitting in the hotel?
