The best I can tell, "kombi" is just the way they say "van" in Africa. We rented two of them in order to accomodate all 16 members of our team. And we went everywhere in them. They were perfect: spacious, reliable, and sooo darn cute. Plus they had license plates with elephants on it!
We only had one unfortunate event during the duration of our stay. The very first night we were there (!) someone shattered the window and stole our GPS while we were at dinner. You can imagine that our team was a little shaken, being that it was the first night we arrived. But it was a good reminder for us to be extra cautious about being safe!
