We spent 7 days at Port O Call, over New Years with our family, that has kids ftom ages 1 to 9 years. They had a great time, and we always felt relaxed and allowed them room to explore and play.
The campsites were of a good size, bins emptied daily, a lady will wash dishes for a fee, easy 2 minute walk to the beach, clean toilets (although quite old ablution block), responsive owners if problems are experienced.
We camped on site 5, which has a lot of ants and flies, so be prepared and bring doom if you cant handle them, as much as its part of outdoor camping.
There is 220v power, no blue adapters needed, and water taps scattered about in close vicinity.
No built in braai setups at the camp, but there are behind the games room, adjacent to the playground.
