In all honesty, I haven't done any research or booking except for purchasing the tickets. I am looking forward to making a plan soon. If you're interested in joining a meetup or sharing tips, please send me a message. 

I am interested in doing a round-trip from Cape town to Johannesburg by taking the coastal route next to the Indian Ocean, which is not a typical route. I'm willing to rent a car if someone else is interested in doing it. Happy Travelling.
