The AKL lodge can be busy, but overall I would describe it as peaceful. The animal viewing areas and pool are large. Also, the restaurants, Boma and Jiko for Jambo house and Sanaa for Kidani Village are off of the main lobby so that hustle and bustle is off to the side.
This is opposed to BC or Poly where the restaurants are basically right in the lobby, and the lobbies are smaller.
I highly recommend AKL period!!
