I will reach Shanghai Pudong Airport at 23:00 but have to wait for my friend who will arrive at 05:35 the next morning. So I have to wait in the airport for 6 hours. Can I wait in the transfer area or the hourly hotel in the transfer area? If yes, how about my luggage. Will it be lost if I don't collect it until 6 hours later? If I have have to come out of the transfer aread and collect my luggage, then is there any place that I can take a rest for the night at the arrive hall for 6 hours?
