Have read through all 58 pages and this is what I've gleaned.

Arriving CVG-CDG in Terminal 2E, CDG to MRS from 2F(1). Should have no problems making a 2:40min connection whether I walk it or take the shuttlebus. Most instructions here say walk it, though both ADP and AF websites say to take the shuttle.

Interesting question from ADP says for "other flights" (as opposed to international flight connections" to go to "entrance 2.04" then take the free ADP Shuttle to 2F. I can find no reference to Entrance 2.04 on any of the maps (interactive or static).

Does the best route depend more on which gate we actually come in on (#28-47 vs. 51-76)? If we arrive at gates 51-76, is it even possible to walk to the Galerie to make the crossover to 2F?)

Anyway, I'm more concerned about the return flight, MRS-CDG-CVG. We only have 90 minutes for that connection. Do we walk it or take the shuttle? AF says to walk it, ADP says to take the shuttle. What does FlyerTalk say?

In both cases, our checked luggage should be checked through to our destinations, but we will have some carry on.
