Will Visitors access to VIP camps w/ escort?

Depends on your social engineering skills.

Kind of funny

The official rule is, VIP wristbands required to get in VIP areas including camping. But the practice is more casual; I'd like to think the gate keepers were using good judgment when I brought along a couple of well-behaved (at the time) friends and family. And some got in there during the Great Evacuation, which was fine; my camp neighbors had my back on that.
Or the gatekeepers were too wasted to care.

They also let hordes of GA wooks with overly active bowels into the special toilets late at night but that is a different story, best not recalled in greater detail.

i'm sure many of them could if they wanted to. 

Last year there were two VIP areas, We camped in the outer ring. It was pretty easy to bring GA friends into our VIP campsite, there was even a place by our campsite that had a gap in the fence, but it was harder to make it into the inner VIP. This year, the map has a single VIP area, so I have a feeling that they are going to keep a tighter leash on the guests.

That being said, if you flash your VIP wrist bands and bring well behaved folks with you, and you should be fine.

Well...are you hot(ish) and do you have fairly relaxed moral standards? 

Just kidding, but couldn't resist.
