I just returned from 6 weeks in Namibia, you can get a holiday flat in Swakopmund. at a very reasonable price the exchange rate was 7.7 to 1 us dollar when i returned in novemeber.
There are several night clubs in Swakop that stay open till 3 am. I thought Swakop was a much nicer town than Windhoek , but there were more girls in Windhoek.
