As a suggestion before you put together you next set plan a story line. Having a flowing story line can do a lot make up some other not-so-good stuff. Fancy done and in-out stuff doesn't add to the story.
Was there in 1977. View of the Table Mountain Cable Way tram would be nice, if permitted. Clifton Beach area is nice with a few of the 12 Apostles rocks. Cape of Good Hope is nice, if permitted. Going northeast Jefrey's Bay is nice; storms river canyon is really impressive. The coastal area has so much to offer all the way to Swaziland (I think it's a different name now).. I never go to see private game reserves, but Kruger park was good (no permitted for drones).
