We are on the Princess cruisetour EB5 1st week in Sept. We have 1 1/2 days at the McKinley lodge and same at Denali lodge. I have read it is best to skip the Denail tours and take the shuttle buses into the park. Are they easy to get to from the lodge? Seems I can't make reservations yet but that is what we plan to do one day. Recommendations for the other 1/2 day in Denali and the 1 1/2 days in Mc Kinley?
