After reading a lot of reviews, my wife and I, along with another couple decided this would be an exciting way to visit a glacier. The actual helicopter ride was really cool, and being on the glacier was once in a lifetime.
Unfortunately we were only able to be on the glacier for about 20 minutes which, we felt, was not enough time for the price that we paid. We've barely got to take a few pictures, and the guide was asking us to get back in the helicopter.
We really felt like they could work something out so that the helicopter rides, that are continually going, could leave a group there, go back and pick another group up, while we spend time on the glacier. I realize they need someone there with the travelers, but that is something they could work out.
