仮眠室は仮眠のためのもの

なので、一晩泊まると高く付くはず。

T3
Hourly Lounge があります。

料金まではわからなかったのですが、
投稿に、
I am now in a standard room with no bathroom(300 yuan for 8 hrs). Surprised it was quite peaceful with no interruptions.
There are two beds, cabinets and an LCD TV here(mostly 70 local channels and some foreign ones.. no CNN)

For those transferring from International flights to Domestic, after you have collected your baggage and done the transfer, don't go up and through the security checks!

The hourly lounge is at the public space of the T3-C terminal, so you'll need to exit the area.
Just speak to any of the info staff and they would guide you.

I was "cheated" into checking myself thru the security checks and realised the lounge wasnt inside. But once i made my predicament clear to a security officer, he seemed pretty glad to let me out, probably not the first time.

>この仮眠室というのは、お金さえ払えば誰でも一晩使用できるのでしょうか？

は国家資本主義の国なので、金さえ払えば大抵のことは可能です。

ただし、

>なにせ貧乏旅行。

とは矛盾します。多分、予算オーバーでしょう。

後は、
Rest Room に色々書かれているので、片っ端から当たってみるとか。

結局、娑婆に出た方が楽だし安く付くとは思いますが。
