My husband and I are taking the Heart of Alaska Cruisetour from Faibanks on June 18, 2006...we have been discussing different excursions...can anyone give suggestions of "must sees?" Our stops are 2 nights at Fairbanks, 2 nights Denali, 1 night Mt. McKinley, 1 night Anchorage, Skagway, Juneau, Ketchikan.
