DC is having a party at a venue that charges £25 a head.
Most invitees are people I know the parents or at least have a mobile number so I can chase up RSVPs.
However, there's a few where I've had to give out paper invites with my mobile number on and I've heard nothing back.
I need to confirm numbers with the venue.
What's the etiqutte here - just assume non-RSVPs aren't coming and then risk someone turning up and having to be sent home? Or spend money on places just-in-case a non-RSVP shows up?
