The general misconception about COC is that its really crowded. Plain and simple, its not. HN and other camps may not have as many people per session, but they are also not even a fraction of the size of COC. With the sheer size of the lane COC is in, it's not crowded at all. I barely had to call a drop in all 8 days i was there.
The lift line gets pretty crowded after lunch when the racers get there, but after talking to some other coaches at momentum and HN, they said the line is about the same or a little bigger than at HN and momentum.
And yes, you still get to hang out with all the people you meet and the coaches. If you talk to them, alot of the coaches will show you sweet places to eat and do stuff at if you chill with them. I would believe its the same as HN in that sense.
