ATC Visit like BDiONU said you all have the ID to get airside and would just take just a phone call ahead to arrange tour, you or your airline could do!! I am approach and when we were DXB based, DXB/SHJ/MIN/DWC approach is done from new centre at DWC for people not in the know, we had pilots who would just pop in on the off chance plus EK used to have regular visits not so now!!
