Also 10mn if you walk, as I prefer to do, on the main level, over moving walkways, with a nice view of the tarmac. You just walk to the TGV station from 2D
, cross over to the other side of the building, then turn left for 2E, or right for 2C. At all time, you remain within the building and there is no road crossing involved.
You can shave off 2 or 3mn if you go to the food court located between 2D
and 2B, go down one level, cross over to the other side of the building (there is a post office and a small minimarket to your right, as well as car rental desks to your left) go up one level (there is another food court there, you are between 2C and 2A) and turn left to 2C.
Enjoy your flights
