There´s some distance between things in this country and no one walks around after dark. There´s almost no public traffic, that works anyway, and the MyCiti busses is the safest but only daytime. You will need a car but then you cant drink so the best alternative is to go by taxi preferably UBER app that is one of the safest. We will have a phone with a South African prepaid sim card that you can use in the city to avoid the high costs of data and calling. Going by taxi is cheap and even cheaper if you use UberX in the app. Use the link above to register and get a free ride of 200 rand.
