I am making the trip from Kenai, AK to Redmond, WA. The itinerary has a 13 hour trip from McCarthy, AK to Whitehorse. Is there no place to stop between? 13 hours in a car is a long time.
From McCarthy to Whitehorse it looks like there are places to stay in Tok and also at least one after the Alcan Border Staying at Tok would split the drive into an 8 hour trip and a 7 hour trip. I don't know what the difficulty would be about getting a reservation.
