Remember, when you book excursions that these are small cities or towns. We went "gung ho" and booked two, sometimes three excursions in all of our Alaskan Ports. Completely idiotic! Had we known, we would have chosen 1 in each because they all tended to overlap each other. (again, the cities are small). So....... I'd settle for something that interests you in each town and then do some foot sightseeing on your own.
