I will transit DXB tomorrow expecting to change planes from EK-T3 to FZ-T2.
My luggage will go through as both flights are on the same EK ticket.

So my question is: I think there are shuttle busses airside- how can I use them? e.g.
Can anybody with the right BP just take the bus or is it mandatory to visit the EK or FZ transfer desk before?
How long does it take from T3 to T2?
At which intervals do the busses go?
Where exactly do the Busses depart in T3?
Any nice bars in T2 to kill some time (maybe smthg. with runway view)?

Thanks!
