THIS IS A CATTLE CALL, BE WARNED! When you sign up for your "appointment" online there is no mention of the fact that the time is irrelevant - the time is just for the organizers to know how many to expect throughout the day. As long as your appointment was confirmed, your good to show up at any point that day (don't speed to get here!)
You will stand in line for about 20-25 min so prepare for the weather - had it both rainy and sunny while my wife and I waited.
I am still in line waiting to "check in" (I have no idea what to expect at this point) and will try to post an update as soon as I'm out.
NOT well organized, and they LIE about what type of event this is by not TELLING YOU when you sign up! BE HONEST about what this is so people know what to expect!!
