Browse and read through brief overview of the airport along with user-submitted review on safety, facility, photos (where available), etc. A must for solo or women travelers who may have to experience such a situation. I personally have used it a couple of times when I had to camp overnight at airports ranging from Paris- Charles de Gaulle to Hamburg International airport and wanted to make sure that the airport even allows people to camp over.
