I'm hoping anyone who has traveled on the South African Elegant Adventure can settle some confusion on my part and tell me what kind of outlet adapter/converter is needed on this trip. I have seen in a tour book that it is an F or L adapter that has either 2 or 3 prongs in a row. However when looking on Amazon to purchase one I find that the three pronged adapter in a triangle pattern is supposedly the correct one to buy. Also what is used in Sabi Sands resort and at Victoria Falls? Thank you
