We are planning a trip to southern Africa in Feb/March of next year and are working on a complicated itinerary. We are hoping to spend some time with family in Pretoria, some time around Capetown and the winelands, want to visit Etosha and the dunes in Namibia, hope to spend time in the Okavango Delta, see Vic Falls and spend some time in Kruger Park. We did some of this trip 4 years ago but were flooded out of Namibia. We plan to take some short flights and rent a car when necessary. Any tips on crossing borders with a rented car? Can we drop a rental at a different point than the pick up without too many problems? Any comments would be appreciated.
