Concerning the hugeness of the airport, indeed it is huge but that's not a problem because you don't need to do long walks to reach your gate or whatever actually. Everything was pretty well indicated in english. I really didn't like the behavior of most workers, though. I felt like the foreigners are differently treated from local people, they rarely say "please" when they ask you to do something. When they want you to move somewhere (else) or stay somewhere (else) they don't tell you anything but start to make gestures with hands to make you move. They're rude and impolite so be prepared for that. Also, a lot of them look worn out and bored (give them some rest!). I've never seen such a big airport with such a bad wifi! We had a one day's layover in Beijing and we took about 3 hours to finally leave the airport. Otherwise, it was a good experience. You clearly feel that you're in an other country, China. But I still recommend that airport (at least one time in your life!).
