Good. The only good weddings I've ever been to (including my own, which everyone who attended agreed was lots of fun) have been pretty laid-back affairs that were just big parties with a small ceremony at the start.
Here's how ours went back in 2000: We're atheists, so there was no religious ceremony, we got married by a lawyer named pro-tem judge in the same place where the reception was, a ballroom on the square downtown in the college town we were from. My wife's dress was pretty but not expensive. She wore a veil that was her mother's (her engagement ring was my grandmother's). My tux was rented. The catering was done by my wife's aunt. We got a nice but inexpensive cake from a cake maker who worked out of her house. The alcohol was a case of Asti and a keg of Killian's Irish Red. The "DJ" was a 50-cd CD player on random. This was before smartphones, so we gave all the tables disposable cameras. We got a professional photographer to take just the wedding portraits and no other pictures.
I don't know if they still say that now, but back then, after it happened, my friends kept telling me that it was the best wedding they had ever been to.
Honestly, the only thing that didn't go well (other than my dad being his normal overbearing self during the rehearsal) was that my feet were killing me in those tuxedo shoes and I didn't think to bring a change of shoes.
My wife changed into her Doc Martens, which look awesome with a wedding dress by the way.
Always bring a change of shoes to your wedding.
