The biggest luxury in long-distance travel is the possibility of a fully flat bed to sleep on. I have done too many bus & air journeys to now crave for this in quiet desperation, everytime I have an overnight trip. So when flat-beds came along in the business class of long-haul airlines, I was an early adpoter, scrounging around for any loose mileage point to get an upgrade. Later, I found flat-bed configurations in inter-city buses in India. But since most of them are crummy, unkempt buses, I am not too enthusiastic (although the idea is fundamentally appealing).
Yotel is a chain of hotels that combine the virtues of business class flat-beds with those of Japanese capsule hotels. Dreamt up by Simon Woodroffe, the founder of Yo Sushi!, these hotels promise to give the weary long-haul traveller a decent & inexpensive place to sleep while in transit. The first hotel opened in Gatwick. The next is due to open in Heathrow. Eventually they plan to open these hotels all across London. Will they work away from an airport? I dont know.
