Yes, several times. Key, is to allow TIME. I suggest 3 days, so to have time for a fly in/visit of Kennicott/McCarthy. Then necessary in my opinion is another 2 days at Valdez. Many times, people just don't allow the time needed for this area and essentially marathon their way though missing most of it. IF you don't have the time, then perhaps, using what you have elsewhere would offer you much more.
