Maglev and Subway from PVG to Marriott Courtyard Xuijiahui

I will be arriving at PVG and staying in Courtyard Xuijiahui on Hongqiao Road. I would like to try the Maglev and then the subway. Can you please provide me with directions? Will I have to walk far from the subway station to the hotel? Is it better to take a taxi once I get off the Maglev on Longyang Road? If so, what is the cost of a taxi? Thanks.
