DC party invites sent a few weeks ago, should I msg parents to reconfirm attendance?

[Kittenmumma]

Sent the party invite almost 2 months before the party itself (it seems to be the norm in DC’s school) and most people had immediately replied saying they’ll be there. Party is in 10 days and I need to give the venue accurate numbers, is it acceptable to msg everyone asking them to confirm attendance? I am thinking 2 months is a long time and some might have forgotten or taken other commitments so I’d like to message them again but not sure what the party etiquette is?

Message and ask them if their child has any special dietary requirements. That'll remind them.

Absolutely - message them today for catering / numbers purposes and then the day before or early on the day with a “look forward to seeing you” so people have relevant details handy and don’t have to search (include tips on parking, post code, any venue quirks) . Many many years of event planning both with work and family. While the organised folk will think the second message overkill and just ignore it, the people with ADHD, stress, family stuff going on or just chronically disorganised will thank you for it (I have had MANY people thank me over the years).

but you absolutely must send at least some kind of reminder in the next few days - one invite two months ago is not enough. I usually count on 10% drop outs, even just for absolutely genuine reasons (higher percentage if I’m dealing with a flakey crowd or it’s winter and people more likely to be ill)

Yes, this. Assume they're coming and ask if any dietary requirements. This will prompt them to let you know if they're not coming.

But make sure you phrase it so they need to let you know either way, not only if their child has allergies etc
