  I will arrive from Hong Kong to Pudong airport late at night and next
day I will take an international flight from Shangai to Mexico City in the
morning, We have Mexican passports.
Some questions 
1.-  When I make my check in at Eastern Airlines counter in Hong Kong do I have to show my Visa or just when I arrive at Pudong Airport at inmigration. Can I be denied to aboard the plane.
2.- The Airport Hotel is considered inside the Airport or only the Hourly Hotel.
3.- Do you have new or late information about CHANGES  in the 24 HRS VISA EXEMPTION for the transit passengers in Pudong Airport. 
  Our travel agent told us  that:  "aliens who hold passport from other
country do not need Chinese visa when they will stay in a Shangai airport
transit city for less than 24 hours without leaving the airport.
