I have used CDG twice as a hub airport, both times with very short layover. Each time a minibus was waiting for me at the aircraft and took me round to the departue aircraft. No hassle, off one plane, into departure lounge and onto connecting flight. Bags made it too. Very professional.
On the way home, 3hr wait. 3hrs in CDG is enough for any man to have to endure. Terrible place.
