When it was time to go to bed we changed in our lockable booth. Put on thin thermals, warm pants, a sweater, a wool hat and mittens. We had to wear our boots to walk to our room.
Picked up a sheet and a warm sleeping bag. To stay warm during the walk it was recommended to wrap the sleeping bag around you.
Once in our suite, Warm Up, we took off our boots and crawled into our sleeping bags. There are mattresses and a rain deer skin on top of the ice bed.
We turned off the lights, there was a light switch by the bed, and fell asleep fairly quick after a long day.
