Mexico City - Inside Mexico City's bustling airport, weary international travelers seeking some peace and quiet can now roll right into bed.

The airport has joined a growing global trend, offering a pod-style capsule hotel for frugal travelers like Alonso Gutierrez.

"Staying in any other hotel, with the same comforts, would have cost about $110 to $170 USD a night. The prices are very, actually quite reasonable here," said capsule hotel guest, Alonso Gutierrez.

For about $30 a night, you get not only a bed, but a bathroom and a locker for your luggage. And at six feet long by three feet wide, the capsule fits most travelers.

The concept started in 1979 in Japan. That's where hotel manager Jose Martin says his capsules came from.

"We had to make significant changes because the capsule hotels in Japan are very oriented to their own customs and not so much to tourism. This (Mexico City capsule hotel) is designed for the times and necessities of those travelling in a plane," he added.

Necessities that include a good night's sleep before taking off for their final destination.
