Be sure to consider the pm train if offered so as to allow you time to take one or more of the free walking tours of Skagway offered by the Park service. In Juneau- consider the Alaska state museum or the Juneau Douglas city museum, both worthwhile, and the free self guided of the capital (if still offered due to security?) a farther walk is the Last Chance Mining museum. Pass by the governor's house- nice totem out front. Ketchikan- pick up a walking tour map at he dock visitor center- head up the Fox funicular ($1-2) and out back there are a collection of poles, walk back via the "married man't trail) head up Park to the small hatchery and Totem Heritage museum- worth the combo $10 ticket, cont through the city park and return via Deermount- good look at residential areas. Worth while as well is the Tongass Museum, the city and Creek St are interesting as well.
