I know choice between 2wd and 4x4 for self-driving tours of Namibia has been heavily debated previously, but I was hoping to get an opinion about this specifically related to our trip to Sossusvlei and either Namib Rand or Swakopmund (haven't decided yet). If we visit Namib Rand we were considering staying at Wolwedans Dune Camp and I've read the road from Sossusvlei to the Dune Camp is very rocky and requires a 4x4. Can anyone confirm this? Can someone also tell me what the road condition between Sossusvlei and Swakopmund/Windhoek is like? My girlfriend can get a bit carsick on really bumpy roads (gravel would be ok I think), so an opinion about whether the road travel would be significantly more comfortable/less bumpy in a 4x4 would also be much appreciated.
Thanks all in advance.
