You've already received excellent replies. Let me add that your U.S. passport is the best identification you can have. If you consider that it's valid for ten years, the cost annually is minimal - less than the price of a couple of drinks.Does a person need a passport for Alaska cruises that leave and return to Seattle?
If you take a cruise from Seattle to Alaska and back, it is very unlikely that you will be traveling on a US Flag ship.I was just wondering because it doesn't seem like a person would ever be leaving the U.S. since Alaska is part of the U.S.
Thank you for the information.
