My ds has his 3rd birthday coming up, and I've arranged a party for him. Only issue is, the spaces are limited - 20 kids max. I've paid for 16 children, because that was the 'package' (i didn't read the small print and thought it was for 20 children), extra kids cost £5 each (which is less than the party venue charges 'normally').
I know a couple of his friends have siblings and I'm now worried that they'll come automatically and then it would be embarrassing for me /the parents and upsetting for the kids.
Would it be cheeky to invite the 16 friends and put on the invite that siblings are welcome but will cost £5 and could they let me know beforehand so I know numbers?
I can't really afford to spend much more than I have already and picked this place because it offered a bring your own food option (my ds has multiple allergies so I couldn't get the usual nugget and chip option that these places seem to offer). Switching venues isn't an option.
