Okay I apologise I have done a search and found many threads with directions from T2E to T2F but I still find them confusing so I really would appreciate it if someone can help, I do know reoccurring questions on forums can be tiresome

.
My daughter and her friend are both arriving in CDG term 2E, one from Manchester and one from LHR, they are then going over to term 2F to catch a flight to Peru. They are both due in about 5 minutes apart. Where would you say is a good place for them to meet up, do they need to go through passport control? I believe there is a walkway between the terminals, am I right in thinking they need to go to the lowest floor where there is a tunnel between the terminals and there they will find automated walkways as its quiet a distance and they haven't got much time?
I really do appreciate any help that I may get, I've not been to CDG for over 10 years so am totally unfamiliar with the airport now, as the girls will have only just turned 19 I worry about them. Thanks
