Shanghai FerryMetro/Tourist Tunnel Questions

Staying at Shangri La in Pudong. Wondering whether the ferry that runs from below there runs as late as 10 pm. If we want to go over by ferry and come back by tourist tunnel or metro, do we have to head back by a certain time? When does the tourist tunnel close? Which metro station is closest to where the ferry takes me in Puxi? I know what station is closest to the Shangri La (line 2 - Luj.) but not much about what our options are in terms of getting back and forth between the Bund and Shangri La at night. thanks
