Africa Here I come

My dream of seeing Africa will be coming true next year. I have booked my trip for next March. I will be spending 3 weeks on South Africa. I'll start by spending 4 days in Thornybush then back to Johannesburg to join the rest of the tour as we head to Zimbabwe (3 days), then to Zambia (3 days), Botswana (3 days), Okavango Delta (3 days) then back to Zimbabwe and Victoria Falls (2 days). I'll be going on games drives twice a day starting a 5 am. I'll be in tents but tents with bathrooms and showers.
