We're starting to get RSVP's back and people are bringing +1's and their kids. I guess our subtle and polite approach to only addressing the invitation to the invited people wasn't obvious enough. Kicking myself now for not ignoring etiquette and saying no kids allowed! What do you do if you're getting close to max capacity for your reception space? Start calling people. Ugh! Not fun! I guess we'll see how it pans out but I'm a little worried.
