Hi, My DD is organising a 17th birthday party at home. She's not bothered about alcohol herself, but as some of the guests are already 18 (she's young for her year) they may bring their own. She thinks it's a bit embarrasssing to ban alcohol completely, but says we could ban spirits, as a lot of people do that. She says she is deliberately not inviting anyone who drinks a lot, as she doesn't want it to be "that sort of party". Any tips/advice?
