"be very cautious if they rent the back igloos, yes the night was cold, and yes we were warned to dress appropriately. they said that there was a room heating in the igloo, but the room heating didn't work properly, as it could go on the highest it could and I could touch the room heating with my hands, my room heating under my writing would give more warm than what the heating in the igloo. Even with full blown winter clothing scarves gloves it was still very cold almost unbearable."
