We stayed in the Le Meridien Douala hotel.  The hotel is in the center of the city surrounded by a lovely garden that shields the hotel from the noise of the city.  The Wouri River flows by the hotel and provides wonderful vistas.  The food at the Wouri Restaurant in the hotel was good.  I'm not one to actually ask what's in a native dish, but everything tasted good and I did not get sick.  (In Africa, that's saying something).  Now don't think that we were roughing it in the least.  The hotel is very modern and the staff went out of their way to provide very good service.  It is just so very hot in Douala, I'm not sure I'd want to go back.  It's so very near the Equator that it's hot and muggy all of the time.  Always were sunblock.  Take a higher SPF than you would normally.   Be very careful when you go out to make sure that you watch your step.  I'm not referring to animal waste but rather scorpions and other creatures.  Always watch before you step.  Also, the traffic is crazy.  Naples, Italy and Paris, France are organized by comparison. Overall, I'm glad we went, but I don't think I'll go back.
