On our trip we were the only couple, all the others were single travellers, something that made the trip varied, everyone was included. Don't miss out on the oportunity to experience Namibia if you can't find anyone to accompany you.
The night drive at Etosha N.P. was a great extra as you saw the animals in a more natural setting, behaving as the would if you weren't there. Don't be scared of the dark, its another world but worth the late night!
The camping was a great way to experience Africa. Quality tents & fresh local homecooked food. It was so peaceful and quiet, worlds away from city life. The night sky was not covered by western light polution, an atronomers dream.
The craft market was a great place to get African knicknacks, be warned that the stallholders are persistant and can be pushy if there are not many tourists around.
