At night, the Emirates business class lounge in Dubai is like a hospital. Every hour or so, a young woman in uniform wakes you up for no discernible reason. Well, that's not completely fair. They check boarding passes periodically to make sure you don't sleep through your flight. But that does prevent any semblance of serious rest for the myriad travelers who have late night layovers.
For example, we landed at 9:30pm and will be heading on to Johannesburg at 4:25am. When we arrived, we had our pick of couches to rest on in this gigantic space. But now (at 3am), the place is packed. Uh oh, here comes another uniformed young woman to tell us to put our feet down so they can squeeze in even more weary travelers.
