Introduce the two families without handing anybody a microphone.
At a Cashiers welcome party I’d seat a friend from each side at my table. Give one the choice of card and the other the job of keeping me honest. They’ve learned each other’s names and acquired a common suspect before the wedding party has finished checking in. The next group can join a new round instead of trying to work out what they missed on the first shuttle.
Give the driver one address and the magician one door.
The Village Green’s Commons and gazebo have different entrances. If an invitation uses the Green as its landmark, a pin in the middle of Cashiers won’t tell me which room you’ve booked. Send the venue name, the door for setup, and a planner or host who knows where the station belongs. That applies just as well to a house reception outside town.
Reserve a corner away from check-in and ask the planner to signal me before the toast. With younger relatives at the wedding, make this an adults-only hospitality room or book me for the grown-ups’ welcome party the night before. A wedding weekend comes with enough seating negotiations; I’m happy to settle this one in advance.
