Thank you Tony for this suggestion, I was not aware of these places....I will check them....you know, when it is the first time in Africa, one wants to see all and go everywhere, but this is obviously not possible. I want to see those fantastic dawns and dusks of Africa and the most significant animals...the big five and more...I find so exciting the trip ...I am thinking about taking my D810 with the 200-500 f5.6, 70-200 f4 and 18-35 f3.5-4.5....I am still thinking about taking also my old D300 or try to buy a D500 as a second camera (or maybe a D7500, which is cheaper?)....I heard that tripods are not very usefull there, so an empty sandbag will also come with me..I think that would be adequate for the photo safari

The truth is that there are hundreds of good destinations - apart from the government parks, there are also many many private game reserves, and some of those are huge...
I made my suggestions based on your locality when in South Africa as well as a reasonable budget.
As far as tripods go, if you are after wildlife and birds in the game parks then all your shooting will done from within a vehicle - a tripod then becomes redundant. If one is shooting from a game viewing vehicle then a monopod will be helpful since there will, generally, be nothing to rest a camera and lens on. If you do hire a vehicle then opening the window provides a base to place a beanbag on which to seat a long lens.
Although good sunsets are possible anywhere, the best sunsets, again generally, will be got in the desert areas of Southern Africa. None of the places recommended to you qualify as desert (even during a drought).
Be aware that once you have drunk of the waters you may spend the rest of your life trying to get another taste....
Africa is funny this way!
