That might work in your neck of the woods. Boy, it would not even come close where I am.
The kids had a mass, and a reception.
The ONLY thing they splurged on was the photographer. (That was because I was a photographer for so long and we are a tight little community.)
The guest list was family, and very close friends. Still had 126 people on the list.
My daughter got her dress at a wedding store outlet. Last years dress, retailed at $2,500—she got it for $500 and had to pay for alterations.
No open bar. Two choices for dinner.
Really, compared to a lot of weddings I’ve seen over the past couple of years it was on the lower side of average—and it still blew mine out of the water (30 years ago tomorrow.)
I said “wedding,” not “wedding and reception,” because that was the statistic I had read. The cost of the wedding is the location - many churches charge a very modest fee to their regular congregants - the celebrant, and the license.
I’m not saying this is how it “should” be done, only that it “can” be done, even with many attendees.
I hope your daughter and her husband are very happy.
