I'm going to be participating in the Athens marathon this October. I bought my ticket the first day they were available and got a great deal (I used my employee discount on a frequent flyer ticket roundtrip to MAD, but couldn't get discount on codeshare so purchased the ticket for MAD-ATH, $114 roundtrip first class ticket), only problem is that it gets in the night before the rest of my group comes in the next morning. My flight arrives at 2300 local time and by the time I get through customs and everything, I figured it would be easiest to sleep in the airport, it's not worth the $100 hotel room (plus too late for most transportation). I've read the profile on sleepinginairports.net, but there's only 1 even semi-recent review. Does anyone have any experience sleeping in the Athens airport?
