Plenty of camping! There is a caravan park just 100m away from the park where the event is (1st link), or you go to Pambula (2nd) which is a nice one next to the beach or ...or .
You have to drive from Pambula which is a bummer when you attend the parties in the evening. So better stay in town and you can walk.
There is also an apartment complex opposite which I was staying with the family (4). You have to be quick a lot of the guys stay there!
