Do you have any advice for potential travellers?
If you're thinking about doing this trip - just do it! It obviously helps to like dogs, although one of our group was not too comfortable around dogs at the start of the trip, but loved them by the end! The food was really good - simple, but tasty and more than enough. I'm veggie and was more than happy with my meals, although there is plenty of meat if you like it.
Before the trip I was really unsure what clothing to take - it has been a mild winter this year, so we were fine with layers of leggings, fleece and down gilet/jacket, but in colder conditions ski pants and ski jacket would fit under the Arctic overalls provided. Two pairs of thick ski socks were sufficient for us, but disposable hand/foot warmers would be needed in colder conditions. The hat provided blew off my head within 5 minutes (could just be me), but I'd recommend a fleece headband (to keep hat in place and keep ears warm) plus one or two hats on top. Head torch is essential. I appreciated my ski goggles in the high winds, but sunglasses would be sufficient in less windy conditions (but not great if not sunny!).
Definitely try the sauna and rolling in the snow - actually much more fun than it sounds!
