Exploring the world’s strangest hotels is certainly a fun thing to do, given the extremes hotels have gone to, just in the name of being “strange”. And strange they are, too, by the looks of them. Ask anyone who’s been to a hotel from the list below, and he’ll tell you first-hand the experience that comes in staying there. Here is a list of the top 5 strangest hotels in the world. There are lots more, but only these five have made it to this list, based largely on popularity, service, and my own personal experiences.
5. The  UFO Capsule Hotel, Tokyo  Japan
Certainly one of the strangest concepts ever for a hotel, The UFO Capsule Hotel is a chain of “capsule hotels” across Japan that has been around for quite some time and has gained immense popularity as well. The concept of the capsule hotel may as well have been derived from the Japanese mind, given the way it uses space so efficiently. The Capsule Hotel consists of small “capsules”, which in turn have two sections: one, a public lounge space, and the second, a private sleeping space. Less space doesn’t mean throwing away amenities: TV, adjustable lighting, radio, all are present. A must-stay for those seeking the “strange”!
4. IceHotel, Sweden
Do not get surprised: the name of this hotel is exactly what the hotel is made of: ice. 
Open only in the winter, Ice Hotel is unique: it stands as a hotel in the winter, and melts to become a free-flowing river after the cold is gone. So that means the hotel is essentially built every year, and then it melts away after the sun comes out, only to be rebuilt the next year. Located just 200 kms north of the Arctic Circle, IceHotel is built by artists who come from all around the world, and by using only frozen water (ice) from the Torne River. Furniture made of ice is present, and beds are made of ice too, and covered in reindeer skins.
3. Hotel Fox, Denmark
Hotel Fox is one of a kind, and you certainly have not seen anything like it, that’s for sure. The hotel has 61 rooms, and each room is an exquisite piece of art. Combining the brilliance of 21 artists drawn from all over the world, and after studying close to a thousand different ideas, Hotel Fox was transformed with themes in each room as unique as possible, ranging from flowered themes to friendly monster themes to fairytale themes! The food at Hotel Fox is always being innovated, by inviting the best students from the best European cooking schools to prepare food under the supervision of experienced chefs.
