To take shoes to walk in rather than the boots is everyone's choice. You can change footwear at the landing sites. Today some did that but most wore their boots. They said that if anyone wanted to do that they could and that they would advise if boots were required on the walk before each landing. I stepped in a mud hole so I was glad I had on my boots.

I did ask about the Narwhal sightings. He said they are very shy creatures but it could happen. There are definitely areas that have a lot of Narwhals it is just whether we get to see them or not. I really think these expedition leaders answer these types of questions two ways. One with enough enthusiasm to get you to take a voyage and then sometimes the opposite not wanting to raise expectations.
