Many IHG properties are close to the subway line. PVG is directly connected to subway line 2. Riding the subway, even with luggage is not difficult. Signs in English...
Riding the Maglev was anti-climatic for me... But if you do stay in the area, and are interested in sporting/outdoors equipment, visit the store DECATHLON near the station. Their products are decent and relatively well-priced for western-goods quality.
Taxi from PVG to most IHG properties will cost over RMB$100. Bring a print out of the address in Chinese before landing. (Doesn't hurt to have the local phone number (not toll free reservation number!) as well. Don't assume the taxi know where your hotel is... especially with generic name like "Holiday Inn" or "Intercontinental".
