Due to the max capacity of our venue, we can't allow our guests to bring their children (those who have them). It absolutely has nothing to do with our budget as we capped it at $35k and we are so below it. However, the venue I liked my FH didn't because of the distance and he felt guests wouldn't travel too far. I myself, didn't think it was that far but, I gave in because I realized there maybe something down the line I may really want and it's better to choose your battles wisely.
The venue chosen, FH fell in love with immediately and we've already got the contract on but max seating capacity is 200. With that said, we have family members we know will not follow etiquette and go by whose names are written on the inside envelope nor the number invited we will have indicated on the RSVP card. Is it appropriate or in poor taste to note on the invitations "Adults Only"?
