We toured SA in Sept 2006, from Pretoria to Cape Town by Mercedes Overlander for 3,500KM, & stayed at chalets throughout the 3 week journey. Kruger was covered in 3 days, staying at chalets. Accomodation varied from huts to big air-conditioned self-contained apartments. Shukuza, Huluwali, Niemsiella, Umfulozi, and a few other names come to mind. The most exotic was one where we stayed in "beehive huts"- round thatched roofed structures with brick extensions for individual bathrooms & toilets. The "door" was just a sliding wooden piece that locked from the outside, & we had to lodge a heavy bag there to prevent outsiders from coming in. Most cooking facilities were available.
