I stayed at the South KOA last summer and used their shuttle to downtown. Very easy. Before doing any walking, I wanted to have some idea of where I wanted to explore so I did the double decker bus tour. Headphones provided properly sequenced location info in the language of choice. You can get off at any stop and explore at your leisure and get back on the same or a later bus. Enjoyed OQ very much as it was one of the highlights of my NB, Nova Scotia (Lunenburg another highlight), PEI (lowlight), Gaspe Peninsula and Ontario part of my trip.
