I have to wait for 19 hrs at PEK. Where is Round-the-clock- hotel room in the terminal building?

You can find Hourly Lounges in all the terminals.
In T1, it is located to the west side of the entrance gate 8, 3F. You can book a room by dialing at 86-010-64540985.
In T2, it is located between gate D2 and D3, International Arrival Hall, B1. The telephone number is 86-010-64598943.
In T3, it is located to the west of public area, Arrival Hall, 2F, T3-C. The telephone number is 86-010-64558577.

Thanks so much, Ross
