I'm having a birthday party a week today for my daughter's 6th birthday. I've invited all her class, 19 in total. The invites were sent out on 21st June as we went on holiday the following day and the kids weren't at school for the last two weeks before start of the summer holidays (we live in Scotland). I stated on invites to RSVP by today 28th and so far I've had 3 coming and 2 not able to make it. I understand that it's the summer hols etc but it frustrates me that people don't reply. I've resorted to inviting some of her big sisters friends to make up some numbers. I've booked an inflatable assault course at local leisure centre and arranged for local cafe to do a kids buffet. I've ordered sweetie scones and big bubble wands today as favours and I've ordered extra incase some kids turn up who's parents haven't bothered to reply. I thought at one point about cancelling the party but it would break my wee girls heart. I've been tempted to put a vent on Facebook about parents not replying. I texted one of the school mums yesterday asking if she knew some of those who hadn't replied and if she could get in touch with them which she has done but still no replies. What's everyone's thoughts on this and what is the current etiquette with parties? I've only ever had one party before for my eldest six years ago and had a couple of kids turn up who's parents hadn't replied. Do people just not bother to reply then turn up?
