The Abadía Retuerta LeDomaine, a Spanish five star hotel, gives guests a pair of Google Glass goggles so that they can get more out of a tour of the 900-year old property, known for his art collection and architecture.
They can obviously also use the device for taking photos during their stay at the hotel, making videos, phone calls, browse the web, etc, as well as watching a video about the hotel.
When a guest checks out of the hotel any files stored on the device are downloaded to a memory stick for them to take away.
