I don't know. If you had 50 friends, reserved space at a decent restaurant, and got a DJ you could totally have a good time for what's been solidly under $10k even until recently in most of the country. Outfits + photographer + rings add, but there's obviously a lot of latitude to have a really fun time in that price bracket depending on what you like. And there are all kinds of alternatives. We have some friends who went to Italy with a wedding party of about 8 people (family and close friends) and had a great time. I don't think it was cheap, but it was probably below the low end of the $20k if some of the wedding party paid their own way and they had a really fun Italian vacation. We also have friends who just borrowed someone's house, got a pile of food delivered and had basically a game night wedding thing.
