Pudong airport to Lujiazui station via Maglev and metro

What is the most convenient way to arrange travel from Pudong airport to Lujiazui station via Maglev and metro?
- I assume a single Maglev Single Trip + Metro One-day Pass purchased from the Maglev ticket office at the airport would mean I could simply connect at Longyang Road without needing to purchase another ticket.
- I'll need to travel back to the airport 4 days later - it sounds like I can buy a return Maglev pass, but that would mean I'd need to purchase single Metro 2 tickets at either end of my journey.
- Is the entrance to Longyang Road/Metro 2 station clearly marked and near the terminus of the Maglev?
