Greetings-My understanding is the fastest and cheapest way from Orly airport (Quest) to our hotel in the La Defense area of Paris is by train. First, is that true? Second, if that is true what is the best route to get there/how do we do it? Also we will have a suitcase and a carry on with each of us. Thanks to anyone who can help us out. Although we are not exactly city neophytes, we unfortunately do not know French so want to have this information before we get there. Thanks very much.
