Our family is taking cruise to Alaska. We set sail next week from Seattle, and I am terribly excited! Research into weather at our ports of call -- Juneau, Sitka, Ketchikan, and Victoria -- makes me think that it's going to best to prepare for windy, wet weather in the 50's. But having never been to Alaska or a cruise before, I'd love some advice about what to pack. Help?

Thanks in advance!
