What's the best route from PVG 2 holiday Inn Express Zhabei plz? can I try maglev in between?

Yes, you can take the maglev train to arrive at Longyang Road Station first. Then take subway line 2 to Century Avenue Station and subway line 4 to Main Railway Station, Exit 4. After that, walk northwest around 830 yards to find the hotel. The whole way will spend around 40 mins with the ticket fare of CNY 55 per person.
