The article mentions: that the other contestants couldn’t figure out who was joining them, only that it was someone important. They were all surprised when they saw who came through the door.
It becomes a different trip when the Crown Prince joins you. The security aspect was tightened when he joined, and a security detail followed the Crown Prince everywhere. So it was not only the Crown Prince, the other contestant and the film crew who made their way up the mountain.
The Crown Prince: I enjoy staying on-board boats, and Lofoten is very beautiful. I enjoy trips like this, and I presumed there would be a nice group of people here.
I was introduced to winter sports early and it was my mum who started it all. She got me skiing downhill before I was three. I tried snowboard, but when my friends started Telemark-skiing I did the same. After a while we started going off-piste, and then starting at the bottom of the mountain. And that is what I enjoy most today.
