How would you suggest spending four days in southern Africa? I have some time planned in Harare, Zimbabwe and Victoria falls and a 3 night safari in hwange national park. . After all this, we will still have 4 days remaining. We would like to visit a nearby country (from Zimbabwe) if possible. Can you suggest a "must see"? Which country/city would you suggest visiting? All things considered, what would be the most economical choice?
