I also had 2 days as part of a DONE4 in July 2002 and would have gladly extended it to 2 weeks if it wasn't for other family committments at the time. Although we stayed at the Alyeska Resort in Girdwood, I would have been perfectly comfortable sleeping in the back of the rental car, which turned out to be a Ford Expedition even though we had reserved a mid-size.

Day 1 included decent hiking around Girdwood and day 2 was the beautiful 26 Glacier cruise. Despite some rainy weather, the natural environment we experienced on both land and water was nothing short of breathtaking. If you can stay longer, there is so much more to see and you will not be disappointed (as long as the beer budget stays intact) !
