We didn't prebook anything in Ketchckan but at the pier signed up for a bus tour of the town/totem pole village. It was alright. We also bought tickets for the Lumberjack show which we enjoyed. Ate at a nice restaurant - don't remember the name but it is across the street from the Tongrass building. Other than that we just walked around Creek Street doing some shopping before going back to the ship. Hope you enjoy your trip.
