Thank You ^. Let me digest the real info above - rather than R2r's data.
Flight arrives at 7:25 PM and no set time to be in Tianjin. 9:00PM shuttle and in Tainjin b/f midnight sound reasonable?
However, I don't think I've been in the South station area - looks like it could be an interesting area to explore and spend a night (if Taoranting Park is open late).
Cheers -
