This time I went twice as much as any past years (two nights instead of one) lol. 
I think since I'm kind of laser focused on seeing as much as I can of the event I probably am oblivious to a lot of the incidents that are referred to on the forums,  if I was attending more nights and going at a more leisurely pace maybe I would see more of what is referred to, but I am happy to say I'm either lucky or oblivious.  I didn't notice any bad or overly obnoxious behavior from kids, drunks, drunk kids or anyone in-between.  I did finally see one scareactor talking to guests in Vanity Ball .  My friend did say she saw someone being creepy with the dancers in Hellbilly and a worker shooed them away.  So once again ignorance is bliss!
