Looks like 3 nights in Anchorage. If rent a car, drive down to Seward if you have time.
You can stop off at some Glaciers along the way. I remember visiting a porperty devoted to Hale Boggs that we took a small boat to view some Glacier calving. It was priced high, but I did get calving pictures that rocked the boat.
Anchorage-Smon ad Seiferts I think is the name of a restaurant recommend.
Earthquake park not much, but intersting.
I assume you train to Denali. Nice ride. Denali- two nights plenty enough. Take the full day to do the park tour. I think you might need a congressman's pass to dirve a car in, so do the bus tour.
That's all that comes to mind right now.
