I am usually rather diligent at doing all my homework before turning to FT with my questions, but for this I feel I could benefit from some quick answers before starting my searches for flights/hotels/cars.

I'm thinking about trying to redeem miles for a return trip to either Juneau or Anchorage in July 2011 and rent a car, one of my destinations being Whitehorse, Yukon. I understand that absolutely everything is rather expensive that time of the year...

Will I find rental cars with free mileage at both JNU and ANC and will I be allowed to drive it across the border and back (via Skagway/Haines ferry from JNU)?

(Or would I be allowed to drive a Canadian rental car from Whitehorse into AK and back? I have a European passport if that matters.)

If going to ANC, are there alternatives to driving day + overnight at hotel in Tok + driving day where I can have three shorter drives and find two overnight stops at convenient distances?

Do the car rental rates and accommodation rates in general differ a lot between Juneau and Anchorage, making one of them a more natural starting point for me?

TIA for any answers and suggestions!
