Transfer to Shanghai Wusongkow cruise port terminal

Good morning from Italy.
Nov 12nd we {two persons) will need to transfer from Majesty hotel, downtown Shanghai, to Wusongkow cruise port terminal.
Who knows the cost of a taxi?
I saw that to book a transfer from the airport (PVG), on the web, costs about 50 US dollars; to catch a taxi at the airport it costs less than 25Us Dollard.
What do you suggest me.
Tky for your suggestions.
