Just wanted to tell you that I just visited the lounge at CDG and it went well.
Although I must say it was really tricky to find it, not to mention how tricky it was to leave it in order to find the gate.
And I had been at CDG T1 several times before...
I asked for an invitation from the check-in counter and got one, there was a map at the back but it was incorrect because they are doing some refurbishment in the terminal at the moment, so it just made it more confusing.
A quick stop at the passport control to enter the non-Schengen area and then there were elevators just to the right of a press shop (Relay) in the tax-free area.
The lounge was at 11th floor, to the right when leaving the elevator, next to I think it was the Saudia lounge (no ANA lounge what I could see).
Rather small lounge but adequate with lots of newspapers, alcoholic and soft drinks and tasteful brownies, no sandwiches or food was available though.

Leaving the lounge was even more tricky, the "transfer passport control" between then Schengen and non-Schengen zone was closed so had to use the normal passport control for arriving passengers (with long queues), followed by a long walk around the whole atrium to find the entrance to satellite 7.
Then the usual moving escalator through the tunnel and security check, just made it for the boarding announcement.

I would not really recommend anybody to visit (or start looking for) the lounge unless you have at least an hour (or preferably more time) before your flight leaves. Took me about 10 min to get to the lounge and another 15 minutes to get from the lounge to the departure gate (security incl).
Can't really understand why an airline which flies uniquely to Schengen destinations has its lounge in the non-Schengen area.
Hope they move it in the future.
