hi!we will b visiting macau on sept.5,2011,possible touris spot to visit in 1 day?

There is still ferry back to Hong Kong from Macau after midnight. So, you do not worry about going back. The first ferry available at 7am. I would suggest you go to Macau Ferry Terminal and then visit St. Paul's Church and surrounding area. Then Ama Temple or Macau Tower. Then Venetain. You can go to Rua do Cunha for food, which is not far away from Venetain. Then leave from Taipa Ferry Terminal.
