I recommend walking around Sitka -lots to see for free or pick a tour. In Ketchikan, as Thoth said, Creek Street & Totem poles along the way to & from the ship are great and also free & there are many in Victoria, BC - u might be able to do several if time permits - Butchart Gardens if u like a spectacular flower, tree & shrubbery display in an old quarry with a light display plus spectacular fireworks if u are there in the evening, carriage tour, whale watching tour, a tour around Victoria by sightseeing double decker bus, walking around downtown Victoria - very quaint & English-like & free plus shopping the local, UK & native shops - not free unless u don't buy anything (the handmade chocolates are to 'die for' and don't forget the maple syrup - yummy)!!..You will really enjoy the costumed 'meet & greeters' on the pier when u arrive & look up and see all the hanging flower baskets in Victoria too. Hope this helps & happy cruisin'!
