We usually fly out of 2E which is near 2D, they are pretty good at assisting you through, in case you need it. The transit desk will be in an open area where it is pretty easy to spot. I don't think it's marked though, so when you come down a hall and then into an open area (not super big) with a desk (about 6 agents long). For us, it was on our right hand side as we walked into the area. You'll have to stand in a semi-long line (but hopefully not).

So, what do others do during transit hours in CDG? Any good ideas for places to eat?
