Visa requirements when visiting on a cruise ship.

My wife and I will be arriving on a cruise ship, spending 3 days in Beijing (Tianjin) on 10/8/14 to 10/11/14 on the ship and 3 days in a hotel in Shanghai (Baoshan) on 10/12/14 to 10/14/14, when we return to the United States by air. We desire to see many sites while in China. Will we require a L type?
