Can I get a 144 hour visa from Wusongkou International Cruise Port.

Can I apply ahead of time for the 144 hour free transit for China or do I need to get the 144 hour exempt at the Wusonkou international cruise port when I leave my cruise ship on March 25th 2018 at 7:00am? Four of us will be taken from the port by a private guide and spend the March 25-29 in Shanghai,, We will leave for the US from Shanghai on March 25th 2018.
