Later next month I am flying BEY-CDG-IAD outbound on MEA connecting to UA. I have 5 hours between flights and most likely am not going to want to sit in the terminal. If MEA arrives at 2E, and the lounge is outside of security in T1, what is the best way of getting to T1? Do I take Bus/Train and make the transfer, leave the secured side of the airport at T1(if allowed), and come back through immigration? Or would i be better off leaving the secured side at 2(E), taking the CDGVAL to T1 and going through immigration?
