It is the dream hotel for businessmen who have their best night's sleep flying first class with British Airways. Yotel!, a revolutionary new "spaceship" hotel chain that aims to offer tiny but stylish rooms. Yotel! will provide accommodation that is a modelled on a Japanese "capsule" hotel which offers "box-size" rooms. There will, however, be significant differences to make an overnight stay more comfortable than for those who stay in the Japanese hotels. Each Yotel! will have more than 100 rooms, each just seven by eight feet and seven feet high, with a communal bar and lounge. The hotel, which will hire rooms by the hour, is the idea of Simon Woodroffe, who launched the Yo! Sushi restaurant chain in Britain five years ago.
