Kenya's Jomo Kenyatta International Airport serves one of East Africa's busiest hub cities, and the transfer from the terminal into Nairobi's specific hotel districts — Karen, Westlands, Upper Hill, or the CBD — involves traffic patterns and route decisions that a pre-booked driver handles better than roadside alternatives, particularly for late or early arrivals. For the transfers that most visitors actually come for — airport to a Maasai Mara departure lodge, Nairobi to Amboseli, or Wilson Airport domestic connections to Samburu or Laikipia — pre-arranged road or air-and-road transfer sequences are essential to the itinerary rather than optional comfort.
