There are hotels made out of ice.

These hotels are literally just gigantic igloos. While they are growing in popularity, for logistical purposes there are only so many parts of the world that can have ice hotels. The hotels are made out of real ice, so they can only be located in parts of the world with consistent freezing temperatures in the winter with close proximity to bodies of water (so they have a supply of ice). There are ice hotels in Canada, Norway, Finland, Sweden and Romania. Don’t plan on having a comfortable stay, though. Expect your room to be between 17 and 23 degrees Fahrenheit. The really crazy part is, every spring the hotels melt, and they have to rebuild them all over again for the next winter!
