Hi Robin and Claudine,
I spent two days there during April last year.
The stands are laid out in a grid, so there isn't much to choose between them. In the whole caping area, there were two or three trees, with no grass underneath, so your choices are limited to shade and sand, or grass.
The ablutions were adequate, with gas geysers supplying more than enough hot water. Ther is a smallish play park for kids acrosss the road from the campng area. An added bonus is the on site restaurant (always welcome after spending a couple of hours on the road).
If you are not into hiking, do not waste your time or money by visiting the Royal Natal Park. You can drive through it in a about 20min. The 'Tower of Pizza' on the way there is worth a visit though.
