OMG I did one, For the director of a gallery that I exhibited with, I turned the guy down like 10 times,and even recommended a friend of mine that does them for a living; then I finally agreed to to do it free of charge...
It's a lot like work!
No fun at all, a complete waste of my joy when holding my camera in my hand.
Once the wedding over, you have to go find another one, no weddings no money, I know a very successful girl that gets flown all over to shoot weddings and has developed a great wedding photography business, she hates it, always chasing the next wedding and stressing all the time.
The attached image will bring me six figures, drove to the location a bunch of times over a period of a month, and waited for it, no stress...
I have a very great amount of respect for anyone that does wedding photography for a living!
