Thanks for the great information. Since we will be traveling for a total of 16 days, I was little concerned about laundry and having enough clothes. When you are spending time outdoors it is not always feasible to count on wearing the same pants twice.
In Juneau we are hoping to do the Photo Safari By Land and Sea, which includes Mendenhall Glacier; The White Pass Railroad in Skagway and the Sea Otter & Wildlife Quest in Sitka. We are debating if we want to do the Misty Fjord Float Plane. I'm a little apprehensive after last year's crash. Whatever we do, I'm looking forward to the beautiful scenery.
