Show up at least for 7:15, the wait can be 3-4 hours as they have to take appointmenta as they come and appointments are are all booked which causes the wait...get there at 7:15 you ensure a 45 min wait instead of 4 hours...I was there all day for not doing that
You can go without an appointment. Just make sure you get there early or you'll have to stand in a really long line for long periods of time.
