But note:
1) You will need to wait at gate F1 for a bus and a security officer, because arriving from Qatar, you'll need to go through security before boarding the bus. I have no idea how long this will take you.
2) The business lounge in T2 is inside of Schengen, so you'll miss out on that lounge if you take the bus from F1.
I see this thread has been merged now with some other thread(s), but the one discussing Schengen T5<>T2 transfer is not merged here. There was an earlier thread speaking about that bus transfer at T5 Schengen side under gate 10 to T2 which I too have taken several times, works like charm.
It would be good to have those discussions merged here as well, but nevertheless, it is great to hear the F-gate bus transfer is working despite some doubts in the other thread (I cannot find it anymore by searching)!
