Hi. I'm from the uk. I'm going to Paris on the 29th of august with my husband. We are there for 3 days to see coldplay. Could anyone give some advice on getting from charles d.g. Airport to our hotel. Would it be easier and cheaper by bus or rail? Our hotel is the novotel in vaugirard,montparnassa.we could even meet up if anyones going to the concert. Thanks. Kay. X.
