Hello,
I have a stay in Pudong Intl' airport between change of flights from USA to Seoul, for 15 Hrs, i read that there is an hourly hotel where i can stay,but when i called at the number provided, the person responded that the hotel has been closed. Is it true ? Moreover if i book a hotel near the airport, do i need a transit visa? or is there any other hotel i can stay without leaving the airport.

Thanks in advance.
