from PVG to Baoshan cruise port, better to take a private van for 12 people or public transport?

Well, you are suggested to take metro line 2 and transfer to line 4 at Century Avenue, and then transfer to line 3 at Baoshan Rd. Get off at Baoyang Rd from Exit 1. Walk north for 1 minute to Tongji Rd, Baoyang Rd to take bus Baoshan 29 to Wusongkou Rd, Baoyang Rd. Walk east for about 15 minutes, you will get there. It takes about 2 hours and CNY11 for each.
