@ehBeth,
I worked at a high dollar wedding venue in Austin, Greene Pastures - an historic estate and the home of Yellow Dog Democrats.
Our weddings were never under $30,000 for no more than 250 guests.
Our policy was: 50% non refundable deposit down, net due at the reception.
In 2000, we had a wedding set for the second Saturday in June, very desirable date for a wedding. This party booked carried a deposit of over $30,000.
Two weeks before the wedding, the MiL came in and asked to cancel the date and asked for the deposit back, the bride and groom had an ugly breakup. We explained calmly and decisively, no. It was a major date and we would never be able to re-book another the way we want to book a wedding.
She said: Keep the date booked. And two weeks later we held the weeding ... with another groom. A lot of the guests were extremely confused about who the heck the groom was. Staff had a lot of fun conjecturing how that all played out.
I got some wedding stories, I gotta say.
