Do you have any advice for potential travellers?
We found the snow shoeing very easy indeed, much more leisurely than moderate - the longest walk was only 4 hours or so and the stops were frequent. The only time we felt we were working was when cross-country skiing, which we did our day off. Returning to base for a hot lunch most days (packed lunches were avalable) was a bit of a surprise as we would have hoped to spend longer on the walks, but had it been much colder then maybe we would have thought differently.
You need to buy your lunch every day - the only choice is buy it at basecamp or go without, as there is no choice of venue everybody we spoke to felt that this should be included in the price tag, even if that is then correspondingly higher.
Boots - we took our own but didn't use them. Don't bother, the ones supplied are much lighter and much warmer. Clothes - apart from one occasion where we wore a basecamp outer jacket, we used our "winter walking in the UK" gear. Yes, they supply everything (and it's all washed before handing to anyone else) but I'm usually a Medium size and had to take XXL to get the sleeves long enough.
