Wow, these are amazing photos. Looking to go to Namibia myself soon, so this just is an icing on top of the cake.

Would it be fair to say that cost at Namibia is about the same as cost for South Africa trip? I know it's not to the level of Botswana safari ($$$$)...

The other concern is - what are the options if you dont feel comfortable driving on the soft sand area? Like, I would like to self-drive during trip to Namibia, but I also understand to get to certain areas in the park, you need to go through these non-paved, soft sand "road". This is the section I am not comfortable / experienced doing. Would there be an option to hire another driver (from the lodge/camp perhaps?), once there, to do this portion of drive?
