Changes

It is often possible to sleep overnight in big airports. Airports are '''safe''' and '''warm''' places, in addition you can always find there free toilets where you can wash yourself. Sleeping is generally tolerated by the security staff since many persons have early-flight departures and have nearly no other choice than sleeping there.

Airports are often close to big roads or highways. You may try to catch a ride from someone leaving a parking or a taxi going back to the city after dropping someone at the airport.
