My fiancé and I are graduating from college 7 weeks before our wedding. We are saving for the cost of it and not planning to ask our parents or anyone for help because it's our responsibility. That being said, we don't think we can budget for having beer and wine at the reception since our families are huge and our guest list is at around 300. We've already gotten "the talk" from MIL about how it's not acceptable to skip any family members when sending invitations so we're stuck on that. Is it rude to have a winery come to the reception and sell their wine? Or to buy kegs and cases of wine, but then ask for $1-2 a pint/glass. I'm also quite worried that people will drink and then drive since our reception venue doesn't have accommodations so I thought this may help with people not getting out of control. What are everyone's thoughts?
