I have glacier helicopter landed 6 times, 1 ERA, 3 Coastal, 2 TEMSCO. I've been canceled upon twice for glacier dog sledding and gave up 2 years ago when did the real thing on a winter visit.

I recommend booking WHAT tour you are interested in. But consider the single landing if funds for anything more , impact on your other touring choices. I firmly believe a varied Alaska touring experience is the way to go.

I've done the double glacier landing twice- definately a highlight.
