I can’t help with your transport, as our clients or airline which is normally Emirates, as I tag on work in Dubai when going there sort that. However Cape Town or Dubai I would say Cape Town every time, and go up to Franshook while there. As for places to stay I use Cape Grace but Silo Hotel is also good but it depends on your budget.
Durban is closer to Boer War sites and that sort of thing if that interests, but Cape Town and Water Front way better with great food and wine. Joburg apart from work I wouldn’t bother with personally, and wouldn’t stay anywhere central there.
As for being a White Walking Talking Cash Machine it’s what you are anywhere in Africa or indeed anywhere outside of Europe/ North America/ Australasia/ Japan and a few other smaller states. You were born in a very favoured part of the planet, indeed as I have said on here before you won the lottery of life the moment you were born. Try to be careful and the advice of others up thread is sound, don’t go adventure touring as I call it, when people suddenly decide they want to see a slumb for example, people do, and wonder why they get mugged etc 😂
