This Finnish resort hotel above the Arctic Circle features glass igloos to give visitors the opportunity to watch the Aurora Borealis or the Northern Lights.
If you feel a little too exposed to be able to settle down for your long winter's nap, they have snug cabins too, as well as all sorts of outdoor winter activities: Winter Safari's, Ice Karting (Think Go-Kart), and even Snow shoeing. However, I may have to hold judgment on their claim that "there is nothing more relaxing than diving into an ice-hole." Refreshing? Perhaps. :) "Relaxing?" Really?
If it's all the same to you, I think that I'll stay in my room and gaze at the stars.
