Thanks for your advice. Unfortunately due to a slight booking mess up I have had to cancel my award flight via Windhoek. Long story but a KLM booking that I thought was refundable turns out not to be so I have to fly that one and cancel the award. I'm hoping to try to visit Namibia maybe for a bit longer as a side trip from South Africa in a few weeks. Would I be better off just flying into Walvis Bay instead of Windhoek?
