Hi David, I'd say stick with South Africa! I did this tour in Sept 11 and it was the best holiday I've ever had - beautiful scenery around Cape Town and the Cape peninsula, along the Garden Route. Visiting an ostrich farm and the Cango Caves at Oudtshoorn, the game drive were absolutely fantastic and finally the scenery at Blyde River canyon was breathtaking. I hope you've booked the add-on to Zambia as well, because this was actually better again! The Victoria Falls were brilliant, especially if you take the helicopter trip. The dinner on the Royal Livingstone Express was a great experience, as was the day trip to Botswana (Chobe National Park). If you haven't booked the add-on I'd say you should ring to inquire about it. I originally only booked the S Africa tour, but after reading great reviews about Zambia, I rang JY and re-booked to include the add-on - best decision I ever made! I do hope you do this tour and have as amazing time as I did.
Best wishes,
Bob
