Hello piggybacking this thread since I have a slight variation. I'm coming in from non schengen, then doing a long (13 hour) layover before doing a schengen flight (all business class). Was hoping to do the following but had a few questions.

Arrive, clear customs/passport , transfer from 2e to 2f (looks like this is where the next flight typically departs), go through security. I would like to then go to the 2F lounge to shower, leave my carry on bags in the luggage lockers. Depart the terminal to go to the city. Return to cdg, reclear security, go back to the same lounge grab my bags and get on my next flight.

Would anyone be able to comment on any issues with this plan - specifically:
1. Any issues with going in and out of that 2f lounge twice?
2. Once in 2F, any issues with just walking out that terminal? For the life of me I can't remember with the schengen cdg terminals if it's like in the US domestic flights and you just walk out in the same area as departing passengers
3. Anyone see any issues with leaving my bag in storage for 12 hours in the lounge?

Thanks so much!
