Recently I saw that Abu Dhabi Airport have GoSleep pods that are hired out by the hour. For about $12 an hour, you get a chair that converts to a lay flat bed, complete with shade that helps keep out light, noise and of course, get you away from the crowds. It would mean no more curling up on the row of chairs, tucking your bag underneath you for safe keeping, and slightly dozing while attempting to get comfortable. In my opinion, so worth it. One can only imagine what could happen in a double version. But a family series could be very helpful.
