About "Free Overnight Transit Accommodation" of China Southern Airlines Guangzhou Company

Generally, there are two people in a room, not many people in a room! I should stay at China Southern Airlines Pearl Hotel next to the airport! But don't you mean that during the Canton Fair and the exhibition, due to the shortage of housing, passengers who need this service should contact the Guangzhou public transport department in advance? Then you have to book a room before you go to Guangzhou, or you will be in trouble if you don't have a room to live in. There is no charge unless you need other services!
