A lot of us have had to spend a night (or even a few nights) at airports all around the world because of delays, cancellations, or just because we were too tight (or broke) to shell out for a hostel.
My worst airport for squatting is still London Stansted where me and my mate Kåre had to spend TWO nights in a row with 8 pounds in savings between us...that was pretty bad.
The best I think is still Singapore airport. Comfy lounges, 24 hour internet and cleaners and security staff who are quite willing to let you spread your crap out and crash for the night.
Any others?
The most comfortable airport in the world to sleep in
