We are planning a trip that will take us to Livingstone about mid-February, 2011. We plan to travel across to Windhoek, taking about 7-8 days to see the Chobe River, Caprivi Strip, etc. I contacted Cardboard Box Travel in Windhoek for help and after some initial contact, I haven't heard from them. Is there a way to do this leg of our trip without an expensive car rental? Is there an organized tour that I can't find? Our budget isn't huge - maybe $4000 (canadian $) max. Ideas?
