Having recently spent more than five hours asleep at Frankfurt airport (but also having spent too much money on dodgy ‘airport hotels’ in the past), I stumbled on this intriguing site: Sleeping in Airports. All you might want to know and more, such as the best and worst hotels for sleeping, tips for the best places, how to get cheap food and free showers, and so on. My favourite has to be the tips page.
Some of the more useful suggestions:
If you are travelling solo take a pen and some post-it notes. Write a “Wake me at 5:00 AM” note and stick a few on yourself and the seats around you — it works. People will wake you.
Even if you sleep in airports on regular basis — Do Not Act Like A Professional!!! Act like you REALLY do not want to be there and that there is absolutely nowhere else to go. We find crying helps. Remember, in the airport officials’ eyes “the airport is not a motel.” On the other hand, don’t abuse the system and abuse the airport’s
tolerance of sleepers hospitality. Staying at an airport for days, hanging your laundry in the terminal and cooking on a gas stove only ruins it for others who really need to sleep in the airport.
As many food concessions shut down at night around the time of the last flight, you’ll want to stock up on supplies (water and late night snacks) before everything closes. There have been reports of a few generous vendors giving away their unsold food to airport sleepers.
While there will be times when you can’t sleep, sleeping in airports is not only extreme budget travel, it can be an adventure. Enjoy it! Have fun! Explore your inner homeless person.
