"Go where you would never ordinarily go, and be still there." -Margaret Fuller

I saw that one other student reviewer highlighted the traveling as the best part of this experience. I would disagree -- the travel is amazing, and you visit a huge variety of landscapes and cultural niches, but the real benefit of this program is the experiential learning immersion into a society that is in some ways very different than, and in many ways tellingly complementary to, that of the average American.
Including three home stays--two urban and one rural--and significant community involvement through internships and volunteering, the program is designed to take you out of your comfort zone and expose you to new paradigms and new relationships that could last a lifetime. You'll be travelling and hearing guest speakers almost every day that you have class, including many people who were directly involved in Namibia's liberation struggle. The readings for classes are intense but grounded, and provide great context for the more experiential learning that permeates the rest of the semester. And the travelling (outside of whatever travelling you do on your own, on weekends and/or the week-long break) is always tailored to the course material; there is no wasted gas, in my opinion.
I would highly, highly recommend this semester to anyone open to a new experience and to a wider social conscience. This is no semester in Europe; it's not a pointless excuse to drink (although you can); it's not a sight-seeing guiltless pleasure cruise. You are always safe (the staff, as others have pointed out, are incredibly understanding and supportive), but always experiencing something new, and you live with purpose everyday. If this sounds at all interesting to you, apply.
