My wife and I will be visiting denali on may 20 this year. Our first time toalaska and to denali. The only offerings left for the tundra wilderness tours on that date are at 5 am and 1:30 pm. Which would you choose and why? We are more late night people than early morning people so we are leaning towards the 1:30 tour. However, if the early tour increases our chances to see wildlife, mt McKinley, etc we will bite the bullet and take the 5 am tour.
