Going to Duban on Business and Staying Over in Johannesburg

I knew when I was making my travel plans that I would have a substantial layover in Johannesburg so I made my plans for an accomodation in johannesburg well ahead of time for my business trip.  I enjoy staying over there before I have to head to Duban.  Johannesburg is really beautiful at night and is quite a large city.  There my not be as much to do there as there is in Duban but it is certainly a nice layover.  I take that time to relax and prepare for business.  Duban is a lot of fun and I enjoy meeting with my clients there once a month.
