I've actually been to the first one on the list. The Dickens fair in Daly City is a good time. It's basically a Renaissance fair for a different era, and everyone there is cosplaying that they're in London during Charles Dickens' time (early to mid 1800's). I didn't partake in dressing up, but plenty of people do. The kids had a good time, and they sell (overpriced) booze, so you can get liquored up and enjoy the scenery.
