8 high-tech pod hotels that will change the way you travel

More people are electing to vacation in pod hotels.

You read that right. Pod hotels.

These unusual hotels are pretty much what they sound like: Lodging made up of small pod rooms that fit only the necessary amenities — a bed, lighting, and some storage space. Most of them have communal bathrooms, and some hotels have other perks like spas and cafes.

The trend was born out of Japanese capsule hotels — extraordinarily tiny rooms built into small fiberglass boxes. The very first one was the Capsule Inn Osaka that opened in 1979. Staying in rooms this tiny may not be for everyone, but their popularity stems from a growing desire for cheap lodging that provides a bit more privacy than the traditional hostel.

Here's a look at 8 of the most innovative pod hotels from around the world:

The Ninehours hotel in Kyoto, Japan starts at $49 a night and offers pod sleeping arrangements. But you can also choose to nap for just $9 an hour or just shower for $7 with shampoo, soap, and towels included

Guests are given a locker key upon check-in where they can store their personal belongings.

The lockers are necessary considering the pod assignments change every night. If you want to stay for more than day, you'll have to check out and back in.

The pods have a Sleep Ambient Control System meant to mimic dawn so you wake up easier. Each pod is made of fiberglass, making them stackable.
