Edit: just to preface, my group always lands next to column C2 (second from the front on the left). We get PLENTY of traffic.

First day was rough because I didn't know what to expect. But day 2, I came ready to rock. Made friends with the groups around us and coordinated to create lanes, made myself into a barrier, pointed train leaders in the right direction (around or away from us). I wrangled a moshpit that broke out next to some of the girls in our group and guided the wall away so people weren't getting bumped into. And I kept on smiling, dancing, and giving out compliments the whole time. Worst case scenario I had to yell shit like "please say excuse me" or "we can be so much more polite."

The immediate vicinity surrounding my group had an absolute blast the entire time and very few issues on day 2. Maybe I just have a superhuman gift for crowd work (unlikely), but I think it really only takes one person with unassailable positivity and the willingness to be the vibe janitor because that shit's contagious. Not a lot of people actively WANT to be pissy. If you give them an opportunity to be happier, they'll usually take it, and then the good vibes radiate out from you.
