I've organised a surprise party for my parents at the weekend, it's joint and invites went out at the beginning of March. I do understand that some people would be put off attending by the cost as its fancy dress but apart from that is it really that hard to just rsvp??
I've only got about 25 confirmed out of 75 invited. Three people txt to say they couldn't make it but I've not heard a thing from the rest, so It could be 25 people or 70+, how do I plan for that without the info?
Would I be unreasonable to just cancel due to lack of interest?
