Hotel Kakslauttanen in Saariselkä, Finland, 250 kilometers north of the Arctic Circle, offers several glass heated igloos as part of its Igloo Village. This is made of a special thermo glass, the igloos maintain room temperature, and the properties of the glass also keep it from getting frosted over, even when the outdoor temperature drops to -30 C. Although, you can opt to stay in one of the traditional snow igloos, there is probably nothing that compares to watching the northern sky from the comfort of your own bed. One of the privileges of the hoteliers is that Igloo Village can eat a meal in the Snow Restaurant, and take time for a drink, out of a cup made from ice of course, at the Snow Bar. In the morning, it is time for a traditional sauna and afterwards, to cool down, a dip in a nearby ice hole. I think it is time to pack those wool socks, hat, and book a ticket to Lapland. Now that is a good service!
At least it gets off the idea of the ice hotel, it is yet so hyped and hoteliers whole look out for a change at regular luxuries and adventurous intervals this shall be an alternative.
