Alaska: Although Alaska enjoys a high volume of aurora activity, its cruises are not often mentioned as northern lights cruises. During the Alaska cruise season, it's rarely dark enough for the lights to be visible.
Usually not because of the daylight. To see the Northern Lights it needs to be dark, cold and clear out. The best time to see them is in the winter between November - March. Alaska is the 49th state in the US. We do take US Currency, we also take personal checks for deposits and final payments on tour packages and major credit cards like discover, visa and master card. There are three different ways to get to Alaska. One way is flying from the lower 48 into Anchorage or Fairbanks. The second way is by cruise ship from Vancouver and the third way to get to Alaska is by driving the good old Alaska Highway. May - between 17 and 18 hours.
