I've been through CDG several times this year. It always induces a feeling reminiscent of the opening of Alan Ginsberg's poem "Howl": "I saw the best minds of my generation destroyed by madness, starving hysterical naked".

Many, maybe even a majority, of flights involve going from gate to bus to a leisurely tour of the airport concrete to eventually arrive at your plane somewhere out there. On a recent flight from T2E both bathrooms were being cleaned at the same time for the fifteen minutes before boarding the set of buses to go to the plane. For many flights you have to transfer from building to building and leave/reenter security. Try finding the navette/bus zones for going to hotels near the airport if you have to stay overnight for a transfer. Many of the departure areas have fewer seats than passengers on the flight.

Paris is Paris, OK, but CDG is CDG...
