This thread came at the perfect time for me. I found a United reward flight to Hawaii next summer. I left an open jaw to hit two islands and on a whim came back via Anchorage with a two day (really 3 given a 10 PM departure) stop over. Our itinerary in Alaska might look like Pogopossum's.
On another site someone recommended the 26 Glacier tour. Has anyone taken that? How does it compare to Glacier Quest?
