Take along a small flashlight for getting around camp at night.
Also....don't forget to take an electric plug adaptor for South Africa
We took a all-in-one adaptor and it didn't work in SA
+ 1 on a small flashlight but you might also want to consider a headlamp so you can have both hands free as the need arises. I carry a small flashlight and a headlamp in my person in the event that I have to walk back to the vehicle or camp after sundown.
