big groups in tent circles is usually the safest.
But all festivals have several "professional" thieves operating.

1)nick big tent
2)put up big tent on opposite side of campsite
3)spend the rest of weekend robbing other tents and dumping stuff in big tent
4)sort out valuables at the end and leave the rest behind, in said big tent.

not being robbed is almost certainly more luck than judgement, although not having anything to steal in the first place is a good start.
