Great article! I also love the heli, snowcat, and lift served skiing in Alyeska but...
I would suggest to anyone who wants to take a full week at Girdwood to explore some other less expensive options. There is excellent backcountry skiing (non-lift, non-cat, non-heli served) just a few miles away in Turnagain pass and a little further up in hatcher pass.
Get up there and enjoy.
