Hourly hotel or sleepbox at Guangzhou Airport

Hi, the hourly lounges are available at the airport and it is near the metro station of the B1 Floor in the terminal building. As I know, the sleepboxes are available there. However, I heard they are only for first class and business class passengers. The cost is CNY40-50/hour. If you happen to hold economy class ticket, it is suggested to walk into the Pullman Airport Hotel opposite the terminal for a rest.
