yes - getting to Maglev is ok - provided you know the name of the station, and if the taxi driver understands your pronunciation! (The station is Loyang-lu.) If you have bags with you that is usually the giveaway
but you can always get the hotel to help you with the pronunciation or write it down. Someone told me how to pronounce the word for 'maglev' but I almost instantly forgot it. and I doubt the taxi would have understood my butchery of it anyway
