We want to go 3-4 days early to Anchorage. We are thinking of flying up on the 4th of July and staying in Anchorage and then renting a car to go to Denali Park. Sounds like the train ride is much longer. Any suggestions of where to stay in Anchorage, where to rent a car, and where to stay near the park that is nice? Any must do's? Cruise leaves on July 7.
