I figured some campers would answer you so I stayed in the weeds a little so far. I stay with some friends at a nearby cabin during Moondance. My sister camped there last year and we made the rounds in the camp grounds. She was in general. After seeing your last post I would recommend you try reserved your first year. The camp sites are closer together, and they seem to kind of watch each others backs a little better, as well as they tend to camp next each other year after year for the most part. I'm not putting down general, as I know many people who have a blast out there. General does tend to be a bit younger crowd as a whole. Things have disappeared out there, but it is not a widespread issue. It is also a little bit of a walk to get there, where most of the reserved sites are close to the concert area. I am just suggesting that you do the reserved thing this year and maybe check out the general area for next year, but I think you are more apt to have the best first time experience in the reserved area, especially considering you are coming such a distance. Also, I think the VIP will be a good investment for you too. I would still suggest you take advantage of the concert set up and go right up front a few times with the crowd though. That is one of the best experiences MDJ offers.
As far as bugs go, I have yet to see one too. Back at the cabin they will carry you away, but at the concert site and in the campgrounds there are none to speak of. Restroom and wash rooms are the best I have seen at an event like this. The jammers are the coolest bunch of people you will ever meet, and so are the staff. You will have a great time!
