Crowd size

First year going to Bottlerock and I was curious on the crowd size. Not necessarily number attending but more so is it easy to maneuver? Obviously it won't be near stages but in the merch/food area/lines?

I've been to Voodoo fest a few times and Hangout in 2011. I've never been to a Bonnaroo or Coachella so was hoping to get a comparison on size.

Thanks, can't fucking wait!!
