We had about 30 guests at our wedding and it cost us a total of $100 ($25 each to the Pastor, Organist, Janitor, and the church fund). I don't count the white Pendleton wool jacket and skirt my wife wore since she used it many times after we married.
Our reception was at my house, my parents paid for the food, my oldest brother paid for the booze, and my best friend's sister made the wedding cake. All those items were our wedding gifts from those people.
The folks who are still around still comment on how wonderful the whole thing was.
By the way, our wedding was almost 37 years ago and we are still together.
Like I said, my wife stressed over the little things - though I wonder how much of it was her, and how much of it was my mother-in-law. As the date drew nearer, Mrs WBill limited her mother to "one suggestion per day", it was the only way she could keep her sanity.
My family? Everyone came in - all of my grandparents' generation, who were all a hoot. They landed at a local hotel. Booze was provided by a late relatives' estate (that's a story in and of itself). The wedding, quite frankly, was just an excuse for all of them to get together one more time and party. The service and reception at the church were just formalities - the fun was had at the hotel, and at my parent's place the week before and the week after.
