Our wedding site is dry location, but we are planning an after-party at another location. We are doing all of the wedding related activities (hosting a dinner/cake cutting/exit etc.) at the wedding location. The after-party would consist of us socializing with our guests, having drinks, a bonfire, snacks, and lawn games.
We know for sure that FI's family will not be joining us at the after-party - they are the reason for the dry location and will not be thrilled that we are even planning an after-party, let alone willing to show up. We are also anticipating the many of our older guests and ones with small children will go home after dinner and not travel to the second location, but we are inviting and hosting anyone invited to the wedding.
My question is how do we decide how much we need to buy in terms of alcohol and food for the after party?
My friend suggested I put something on the RSVP cards to have guests indicate if they plan on coming to the after-party, but my sister says that will make people think they can wait and just come to the party.
I don't want to be rude, but I also don't want to spend the money for 200 people and only have 25 show up. Suggestions? Ideas? Suck it up and prepare for everyone?
