Is there any way to turn away uninvited birthday party guests? Recently, my daughter was invited to a birthday party that was held at one of those ultra expensive arts & crafts joints. The cost per child is well over $10. When we arrived at the party, the birthday girl's mother seemed quite upset. I found out that the mother of one invited guest had brought along four uninvited siblings. Four of them!!! A similar thing happened to me before. I had my child's birthday party at our house when a neighbor sent her grandson (who wasn't invited) to our house to attend the party. I had planned to do a craft with our invited guests and didn't have enough supplies for any additional children.

Is it rude to kindly explain to the mother/child that the space at the party is limited to just the invited children, offer to drive the invited child home after the party, and turn the uninvited children away? The mother incurred $60 in additional fees by letting the other kids stay. Oddly enough, last year when she had her daughter's party at an indoor playground where she paid one price for up to 20 children, only five kids showed up...
