Daughter of close friends of mine was married recently. She and her husband had a private destination wedding with maybe 20 people tops (parents, grandparents, siblings) in attendance.
They had a wedding reception a month or so later that my wife and I attended. Rented on a Sat night a giant club. There might have been 5-600 guests. 3 open bars, 2 bands, endless shrimp, prime rib, king crab legs. Lots and lots of booze. I counted at least 3 crews of photographers taking pictures. Caterers everywhere. Fresh flowers on each table, an ice sculpture that was 6 foot tall, that sort of thing. It was posh.
Now, I've know the parents of the bride for decades now. I know their background. There's no way they could have footed the bill, or even half of it. The groom's family is loaded, from what I was told. The father of the bride and I were talking, and I mentioned something like this was quite the party. He took a drink of beer, said they didn't pay for it---it was somewhere around 200K---just for the reception.
