If flying coach, aren't consolidator fares still the way to go? In our youth that was always the way we did rtw's, seemingly not much more than half the price, but that was a long time ago.

OTOH an LONE4 ex-JNB cost USD1960 (plus taxes and fees) when I looked a few days ago. Rand is weak and perhaps a bit volatile so ymmv. The South African public game parks (Kruger, for lots of resources and easy access from JNB, being first choice) are a screaming bargain, if you fancy spending a few days driving amongst the beasties in your rental car.
