This was my second visit in 3 years. I would recommend that you use a guide - we used Phillip and he was fantastic, great sense of humour, knew the history and was very patient. Cost was only $3 for 2-3 hours.
The museum is OK by African standards although it is a little disconcerting to have police follow you around the museum.
