Imagine a big house made entirely out of ice and snow. That's what an ice hotel is!
Every year, people in places where it snows a lot, like Sweden, build a new ice hotel. They start by using big machines to make giant blocks of ice, like legos, and then stack them on top of one another to form the walls and roof of the hotel.
Inside, everything is made of ice too - the tables, chairs, and even the beds! It might sound silly to sleep on something made of ice, but don't worry - they put really warm blankets on top to keep you cozy all night.
People go to ice hotels not just to sleep, but also to see all the cool ice sculptures and artwork. There might be a big ice throne, an ice bar, and even an ice chapel where people get married!
But remember, because everything is made of ice, it's really important to wear warm clothes and thick boots so that you don't get too cold. But don't worry, the ice hotel is made to be fun, not scary!
