we went with friends and without children. It was the coldest place that I have been though the winter is supposely a really 'warm' winter.
it was ~-20C, good thing we went prepared with loads of winter gear. Heating pads in the shoes def helped, and we can always thaw out with hot coffee served in ice igloos. The ice and snow sculptures are very impressive. Ice slide will be the last slide I will ever be on. It's just not my thing!
