Are you packing "warm" clothes? I have checked the weather, and its only been in the 50's. Whats are the ships like? Do they keep it warm? im thinking of skipping shorts and sandals....
Alaska is a mixed bag when it comes to weather. It could easily be in the 60's or even 70's when our cruise is there. Or it could be in the 50's. Rain is probable here and there.
I plan to have one pair of shorts, one pair of sandals, a windbreaker, at least one sweater, an umbrella, and a light jacket. It won't be so cold as to require 'warm' clothes, but having the windbreaker, sweaters, etc., will allow layering that can be removed or added to as the conditions dictate.
My experience has been that the inside of cruise ships are usually cool. I like it that way. My wife doesn't. There is that sweater thing again,
