I've transited CDG a few times recently, but never with a connection long enough to worry about lounges.

For an upcoming flight, I'll be arriving in 2E, hall M and departing 2F. The layover is a few hours, but not enough to leave the airport.

Since the 2E-M AF lounge is significantly better than the 2F one, I was hoping I could go back upstairs in the same hall and spend the majority of my time there.

Has anyone done this before?

I'm assuming the 2E-M arrivals -> 2E-M departures will have me just going through security again.

I'm wondering if going from 2E-M departures to 2F will cause problems, since traffic is really designed to go from 2E-M arrivals to 2F.

There's a handful of airports where if you're in an INTL departures area, you can't get out of the secured area without an escort and paperwork. Is CDG one of these?
