We have visited Cape Town and the wine districts before and will only be spending 2 nights there, so have 8 nights left. We will be joining a basic tour in JBurg visiting Kruger and Mozambique, so game viewing and beaches elsewhere are optional.
Last year's trip involved riding local buses from Guatemala via Nicaragua, El Salvadore to Costa Rica so I suppose you could call us competent travellers who love walking and bistros equally. I mention this to indicate we like people-chatting and finding out of the way places.
On to business:
Thinking the Garden Route, Addo perhaps and up to Durban thence via Drakensburg to Johannesburg. Not sure where to spend time and where to press on in our hired car.
