I got there at 1:20 (opened at 1:00) and left at 8:00 (closed at 10:00). Much less people than I expected at opening during October, kinda like the Busch parks, like everyone waits for it to get dark, so if you get there early, you get coasters. People probably do this because I think it's cheaper after something like 4:00, and people with season passes who live close come when they like.
No new updates for the coasters, but about 6:30-8:00-- there were a few people in costumes that looked like they had escaped from a mental jail. It was really creepy, but not "scary". Some others thought it was, but it wasn't... anyway, they didn't really talk, and seemed like they were possessed or were half-awake. There were was a show in the middle of the park, right after the entrance, but overall very disappointing. There was a magic show around 4 or 5, but still not that great. Is Fright Fest better at more popular SF parks, like SFMM or SFGAdv?
As I wrote in my trip report, the only thing scary about SFSTL is the tragic lack of upkeep and attention to theme. ;)
