Hi AK first timer,
Here is some information for your cruisetour:
Island Princess inaugural cruise: Jul. 12, 2003, most recent drydock: May 2008
Here is more information on the two Arctic tours (from Fairbanks):
ARCTIC CIRCLE AIR ADVENTURE
The Arctic Circle Air Adventure departs from Fairbanks heading north above the heartland — over the mighty Yukon River, home to Native villages and above Brooks Range where herds of caribou graze on the tundra. The flight traverses gold-mining fields that brought so many people to this land in the first place and continue to operate nearly 100 years later. The stark metal of the trans-Alaska oil pipeline sparkles in the sunlight, clearly amiss in the green and brown landscape, yet striking in its construction; an icon of the fascinating history of Alaska’s Arctic region.
Soon after passing just south of the Gates of the Arctic National Park, the plane crosses the Arctic Circle and makes a ceremonious landing at a wilderness community on the Middle Fork Koyukuk River
. You’ll walk away with a large collection of digital photos and an official Arctic Circle certificate, a testament to your adventure to a land where few have traveled.
JOURNEY ABOVE THE ARCTIC CIRCLE
Fly above the Arctic Circle. This narrated flight takes guests above the Arctic Circle, across the Yukon Flats National Wildlife Refuge, and lands at the Native Village of Fort Yukon
. Athabascan Native guides escort a 1-hour village tour, providing a running monologue on life in the village that paints an accurate but bleak picture of the hardscrabble life here. Return to Fairbanks, catching an aerial view of Fort Knox Gold Mine. Guests receive an official Arctic Circle Certificate upon completion of tour.
Finally, you did not mention it, but if you are booked on the Denali Natural History Tour and you have more than one day there, I would highly recommend upgrading the tour to either the Tundra Wilderness or Kantishna Experience tour. On the National History Tour, it is not unusual to encounter NO wildlifre.

Hope this is helpful. I wish you an amazing trip!
