Two adults, two teenagers each with a rollerboard and backpack/ other small bag: would it be difficult to use the RER from CDG and then walk to this bridge? Our vacation stay is right off this bridge and on the left bank. I have tried to ascertain the distance from the RER site and maps, unfortunately I am away and using a tiny laptop and can't get a map big enough to tell!
Also, is this the line that is notorious for pickpockets? I have no problems with the cost of a taxi, I just hate sitting in traffic and our flight arrives at rush hour on a Friday morning.
