We did two weeks in Alaska a couple of summers ago. Best we were able to do to cut down on costs of the trip for the 4 of us was 4 FF tix on DL, and a few free hotel nights, at beginning and end of trip in ANC. Otherwise, we bit the bullet and stayed in some great places, saw some great sights, and had a great time. Ate those salmon we shipped home for quite a while too!
