Topkapi Palace Skip the Line Ticket with Audio Guide
One ticket covers three doors: the palace itself, the Harem and Hagia Irene, so there is no second queue and nothing extra to pay once you are inside. A host is waiting at the entrance to hand you your ticket, so there is no voucher office to hunt for. After that the palace is yours at your own pace, with an audio guide you can download in advance and use offline in the rooms where the signal drops.
