As to people getting drunk at weddings, it varies. I know I was certainly over my limit at mine, and most people had quite a few.
The few christenings (two) and wakes (seven) I’ve been to, there was a bar at the reception, several of the people had flasks, etc. Usually after the christening/funeral. It’s supposed to be bad luck if you don’t “wet the baby’s head”, i.e., have a snort or two.
And a wake is a thinly-disguised excuse to get sobbing drunk, then magically change into a celebration of the person’s life. Sometimes they’re not even disguised.
Now, to California weddings. Outside if possible, because what’s the point of having the weather if you don’t use it? Quite possibly non-traditional services with interesting people presiding. At ours, we had my wife’s boss, who was a Mthodist minister, administer a Buddhist/Daoist/celebration of life ceremony. My MIL made him a surplice with the yin-yang and an eternal knot on it. Way cool.
One of the best weddings I’ve ever been to was at the Ahwanee Lodge in Yosemite. Ceremony outside with a view of Half Dome, accompaniament by the couple’s friends on flute, guitar and voice (Beatles, man), then a buffet reception in the Lodge itself. Full bar. That’s pretty much the model for the majority I’ve been to:
Outside if possible, casual dress, short ceremony, dinner and full bar. Catering can be extremely casual, like barbecues, and I was actually at one where they got an In-N-Out bruger wagon to do burgers and fries.
Money dance only if you’re Hispanic or Filipino, and electric slide is more common in the north than the south. I told our DJ if he played it he wouldn’t get paid, and the fucker did it anyway. We wound up getting half the fee back after we complained to the company.
