ahhh...
Now i was a first year last year. Their procedure was better.
Basically, they started in an unpublished room (i never got some of the enrollment stuff due to being out of the state, ouch. The paper i missed was about what was happening, and where!), and gave you a map of where to go, and which order to do everything in.
They'd managed to stagger everyone by last name - so the queues, and the experience, wasnt too bad.
To their credit, they started in various parts of E7B, then moved towards the atrium - all in sequence, with all the tables logically placed, so everyone could get to them.
I didnt see a sign, but am notorious for missing them.
Of course, as to why they couldnt put the 07 stickers, and the concession stickers at the same place, on the same table, i'll never know...
