It's a tight one. Whatever you do, do NOT take the connection bus if you can help it. Especially if you are running late. You are much better off walking it (although I am not sure if the tunnel below e & f is open yet). Otherwise, the following can occur.....

1. Your flight arrives exactly on time.
2. You spend 10 minutes taxiing to a remote stand.
3. You wait 10-15 minutes for a bus and/or for the bus to fill up (AF has an annoying habit of making the first bus wait for the second bus to fill up, being in C makes no difference).
4. You have a 5-10 minute drive into the terminal.
5. You spend 5 minutes getting through customs and to the bus waiting area.
6. You wait 5-10 minutes for a bus.
7. The bus goes around every terminal in CDG 2 before getting to 2F (including the very screwy detour filled roads around 2E.
8. You arrive huffing and puffing at your departure gate about 2 minutes before "departure" and are told "it's impossible, you are late!!"

This ALWAYS happens at CDG. Be careful.

As for Menton, anyone been to the Pirate?
