We are a group of 6 and are planning a wildlife safari/trip to Africa with our starting point being Nairobi, Kenya during the month of September 2017. According to the itinerary received by the various tour organisers include only Masai Mara, Lake Nakuru, Amboseli National Park and Mt. Kenya. I can stretch my stay to 12 days, need some more places to visit, mostly wildlife reserves. Should we consider visiting Tanzania for Serengeti National Park?
