FI and I have been talking about the pros/cons of doing this. There really is just so much more than saying "adults only". Some things we have talked about is saying something like, "the bride and groom would like their guests to enjoy themselves (blah blah), so please adults only" or something. Then leave it up to the parent to decide if their child is an "adult". I mean what am I going to do, stand at the entrance and tell them to leave? No, but at least we got our wishes out there. FMIL thinks its a terrible idea, and would really just end up causing off-putting and hurt feelings, which I can totally see after talking to her about it. We have also talked about having somewhere at the reception where parents can drop off their kids (we would hire someone to watch them of course) so the kids would still be close but unfortunately my FI's family wouldn't use it, ending up in a waste of money.
Question, brides that have done this- how did it go over? Glad you did or wish you hadn't? Also, how do you say that without sounding like the Grinch?
