We are going to Tanzania for the second half of June next year. Now, we've decided that since we are already in Africa, we really should go down to Cape Town when the safari is over. It adds about $600 to the air fare, so seemed like it made sense, because just getting to Africa is about 4 times that amount from where we live.
I'm reading that July is cold and rainy, though. Do you think it's worth going even so? The temp does not bother me as much as worry about visibility - since the scenery is a very important part of a visit there.
