... Within the next week and a half?
DS is having a special occasion birthday (not so much the age as recent difficult events make it special) soon, which includes three nice arranged activities, food, etc, and is rather more expensive than we would usually do. Therefore numbers are limited.
Invitations have gone out, but I remember being quite annoyed last time when a lot of parents didn't reply til the last minute, didn't reply at all, and in one case said they needed a lift on the morning of the party or the kid couldn't go.
I want DS to have a good time, so if someone's not going to be there, I want to fill the space. But I can't afford to just invite everyone and hope some don't turn up. I don't have contact details for the parents, so was going to resend an invite after a week, then give another week to reply. After that I'm a bit stuck, if we invite someone else to definitely make up minimum numbers, I don't want the original kid turning up, as I'd have to either pay extra (which I can't afford) or turn them away. Obviously that would be v cruel to all concerned, but I don't really see any other options. Help!
