We have extensive experience traveling around Africa using the minibus system. I thought we could just show up in Katima Mulilo and expect there to be minibuses headed to Windhoek. Someone told me they heard that there aren't minibuses there that head down to Windhoek, is that true? If so, are there any other options besides flying? I know there's an Intercape bus that makes the trip a couple days after we are looking to travel. Thanks for your help!
