Wow, fantastic Tour. The views and photos are even better than expected (even from a phone). Every seat has a window which bubbles out to get great shots. The ride was smooth and not scary at all, like being in a national geographic movie. Definitely bring a jacket as if land you will be walking in snow with a cool breeze even in August.
The staff was great, very friendly, but safety first and your satisfaction a close 2nd. If there is any doubt on the weather or even if the viewing will be great, they give you an option to reschedule or cancel if you can't. They also provided snow overboots and good narratives on the area during the flight.
Best part of our trip. Will do another trip with them when we come back.
