When you hear the word “hotel,” what usually comes to your mind is a big luxurious building, rooms with a comfortable queen sized bed, a table, and several chairs – almost a replica of our own rooms at home. Hotels were made this way to remind us of this, to show that we can experience the same comfort we have in own rooms even if we are several miles away from home.

But nowadays, hotels have taken in new forms – literally. For travelers with a more adventurous taste, here are some of the most peculiar hotels that have been made for people who are brave enough to give them a try. Read on and be entertained by their out of the box ideas and designs.

1. The Capsule Hotel

This kind of hotel features rooms or rather beds that is just wide enough to fit a single sleeping person. The purpose for such a design was to conserve space. This was first developed in Japan, a small country known for its bursting population; but unfortunately is not gaining that much popularity in the east. Apart from the sleeping space, some capsule hotels also offer lockers for bag storage, internet connection and even a television inside the sleeping space.

2. Eco Hotels

This hotel is known for being made up of eco-friendly materials. Before, eco hotels were only situated in areas close to nature such as jungles but nowadays, more and more eco hotels are being constructed within the vicinity of the city. Instead of the usual building materials such as cement, glass and steel, eco hotels are made up of local wood and stones which gives that added charm to the entire structure. So for the environmentally conscious traveler, this hotel is the way to go.

3. Ice Hotel

The name says it all; this hotel is mainly made up of carved ice. You might think that it should be extremely cold inside, but surprisingly the temperature is comfortable enough for you to have a good night's sleep. The hotels design features exquisite ice sculptures and even has a bed made up of ice. But not to worry, you will be surrounded by thick warm beddings that will ensure you of a good night's sleep. This kind of hotel is carved and remade every year just when the temperatures are right to keep the entire structure from melting.

4. Tree House Hotel

If you want to go back to your childhood days, then the best way to do so would be to stay in a tree house hotel. This hotel literally sits above a tree and would usually just accommodate only one or two people. Just don't reserve one if you are afraid of heights because tree house hotels are usually only accessible by a ladder climbing up to several feet high. Room service is delivered though a pulley and a rope. What are the benefits of this type of lodging? You get to have a very beautiful view of the surroundings for the entire duration of your stay.

So if you want a little bit of a twist to your vacation, then book yourself in one of these hotels and have the experience of your life!
