Unless CC is training you to fly in a C206 or GA8, in accordance with our SOPs, and with specific focus on Okavango Delta operations, I see it as an unnecessary expense for any pilot intending to come to Maun. As recurrent training for a recreational pilot, I think it's ideal. Just my personal opinion.
Every pilot in the delta does thorough orientation, indoctrination and line training. The training captains will teach you how to fly the way that the company wants you to fly. From my experience, the hardest guys to train (and the ones who can cause problems) are the pilots who have "prior bush experience" and/or extensive time on type.
