h1gc,
Sorry for response late. I didn't mention schedule time at all and they didn't bother to ask either. I got there 8:15 on Friday, and there were about 20 people in the line. I waited for about 1/2 hour. But by the time I got out, the hall was almost empty which was around 9am. I guess because a lot of people would like to do it before heading to work. My friend also did on Friday and he told me the same story.
