Once you land at Kiruna Airport in Sweden you are given warm clothes and whisked off by dog sled to this architectural masterpiece that melts every spring and is rebuilt in stages every winter. When you stay at the Ice Hotel enjoy watching the northern lights or spend time at the ICE Bar. Don't worry about missing church because there is one built into the hotel. At night, sleep in thermal blankets on blocks of ice covered in deerskin and wake up to a cup of hot lingonberry juice at your bedside. All that to say, the vacation may not be the warmest one you've ever been on but it's definitely one to remember.
