I'm visiting Cape Town in September and was leaning on the side of not renting a car, but I'm seeing a lot of recommendations lately to do it. Can it really be better than taking transports when it cost about $23/day for the car, gas is averaging close to $4/gallon according to google, and I assume some places may charge to park? On the other hand for example, a transport from Shark Cage diving averages about $30 from what I've seen - so after you factor gas for a rental, the transport is cheaper plus you know you're definitely going the right way...and driving on the correct side of the road. Or is this only being recommended because no tours/busses head down the peninsula to boulder beach and cape point?
