Yes, as Nick has said, this is the best advice.
I’ve been to quite a few MK events and as the event grew bigger with more attendance, the camping and car parking became more disorganized with people pitching up wherever they chose. The RAD team a few years ago, on the basis of the event’s growth took the decision to Marshall coordinate the campsite/parking, this was necessary from a H&S perspective, but also having everything in orderly lines just makes it more comfortable for those camping, gives more space for those showing bikes/selling parts and also better for those walking around looking at stuff.
