You may be in the wilderness, but if you like adventure you will run out of time before things to do.
I loved the dog sledging (you can have your own sledge and dog team), the snow shoeing, the cross country skiing, the sledging etc. There is also the option for extra's and I'd recommend the skiing in Rukha and full day dog sledging. There is plenty of option for free extra's too as you can use the equipment to walk the bear route with snow shoes and do local cross skiing.
You can get away with taking little cash and paying for most things by card at the end of the week. For a remote base camp the food is good, the room clean and warm with underfloor heating and the equipment good quality. The only down side is the taster sessions could have covered more ground e.g. the snow shoe taster guide session had a bit too much talking and not enough walking, but a few of us made up for it with a walk to village after. This was a small issue for an otherwise incredible trip.
