No appointment need ,but you need to be there before 7:00 am ,because now people go early to be on line ,they take xx people now is fast after 8:30 went they open
No you go wait on the line get registered and they text you half hour before your time. Or you can track ETA by texting them. I do suggest going early. I went 7:30 and was 75th in line
