Does this tour use smaller 4WD vehicles for the game drives than the large vehicle used for travel from place to place? I'm a keen photographer and don't want to photograph from a larger vehicle (more movement and more blurry photos). I don't have a travel companion for this trip so have fewer options for trips because I like to have a single room. I want to visit Namibia, Botswana and South Africa in October/November. Any suggestions?
