bruh it's a LONG drive and there is NOTHING in namibia. it's BEAUTIFUL but desolate

but lots of beautiful eco-tourist campsites few hours north of the border, you can find a fully furnished tent for very reasonable, they do eco tourism very well
make sure you take long, 2 night breaks between drives

i suggest yall still do the drive, but have enough padding between the days yall drive

walvis bay is alright to check out but namibia's towns are pretty boring, windhoek is cool for the craft market and that's about it

managed to do windhoek to capetown in a night, man that was a cannonball run

for etosha you can get away with a car but some side roads are not the best for a car. you should have 2wd suv at minimum. if you want to do soussevlei you absolutely need a 4wd or park and have the fellas in the park transport yall in their 4wd (not an inconvenient thing)
