Middle age couple, simple wedding:
We are having a very short, informal, ceremony at a local park at 3PM. We are not sending invitations. We have an event on Facebook inviting family and friends to simply stop by if they are in the neighborhood, "Well Wishes Only".
Then we get pictures done and we have an entire floor of a local restaurant/bar booked for our supper (5PM) where we will continue to party late into the evening with the house band.
We are paying for suppers (suppers only, not drinks) for our parents, sisters/brothers/ and their spouses and kids and for a few people who are coming from far away. (approx. 33 people)
How do we avoid being stuck paying for all the others that might show up? They are welcome to sit with us but I need it to be clear that they are paying for their own meal without making anyone feel uncomfortable. Thank you!!
