The Snow Hotel in Kemi, Finland has guest rooms and and decorations made out of ice. A 41 degree temperature keeps the walls and floor frozen. Its like you are staying in an oversized igloo and going eskimo-style on your stay there.
The hotel has single and double rooms. It also has rooms for groups and for couples on a honeymoon. The rooms range from about $176-$420 per night. The snowy rooms have thermal sleeping bags and shuttles.
Near the Snow Hotel is a Snow Chapel if any snow men and snow women feel like getting married in freezing temperatures. Personally I prefer the beach, but some people are more cold-blooded than I am (pun intended!).
If you want to check it out, do it soon. The snow is starting to melt at a rapid pace!
