My opinion, I don't recommend Saxman without a tour guide. You gain much more with the commentary vs just looking at the totems. AND there are plenty of totems right in Ketchikan if that is all you wish? Requst their visitor guide www.visit-ketchikan.com
Pick up a walking tour map at the dock visitor center. Top choice here, I agree is a Misty Fjord floatplane, I have gone with Southeast Aviation, Carlin Air and Island Wings, Fishing is also an excellent choice, my family has gone out with Northern Lights.
