I am hoping to go to South Africa and Kruger some day, if I can ever afford it (the expensive private reserves are likely way out of my budget). Do you find self-driving through Kruger on a two or three day stay can warrant some good photo opportunities?
Its all about luck, but there are plenty of opportunities by self-driving. I was there a few weeks back after also going to Madikwe on the Botswana border where we drove around with a ranger in a game vehicle, and I found in some ways it was better to have control of the vehicle my self and move into the right position without asking the ranger to move or stop all the time.
Of course he rangers can drive where they like and so can often get closer, espcialy to the cats. But if money is tight, there is still plenty of great opportunity doing it the cheaper way.
I'll post some shots later from my trip.
