Twice we signed up for this excursion - both times it turned out to be a great scenic helicopter ride. We got up in the helicopter but as we approached the landing site, the pilots determined that the fog was coming in and it was not safe to land so we went back to base. Both times Regent refunded 100% of the cost of the excursion. On each trip, our pilot was great and provided wonderful commentary and even though we did not get to the dog camp, we still have a wonderful time and if I ever again have a chance to take another Alaskan cruise, I would most definitely sign up for this excursion again. The groups that left earlier than us were able to land and from their pictures, if my memory serves me right, there was plenty of snow and the sleds were not on wheels. However, this was ten years ago and I don't know if anything has changed.
