What a great idea! Pay the fare once, climb aboard a big open-top double-decker bus, and cruise all over Istanbul getting a sense of the city and the lay of the land, hopping off the bus when you see something interesting, hopping back on after you’ve seen it.
Consider, however, that the fare is relatively expensive(about 30€ per adult, 16€ per child), and while you’re riding, you’re not visiting the inside of the exciting sights you pass.
And, on the other hand, when you hop off the bus to see a sight, you’re not benefitting from the transport you paid for.
Also, that the bus, like any street vehicle, is subject to stoppages in Istanbul’s crowded traffic. If you’re caught in a traffic jam, it’s boring, and you’re still paying even if you’re not moving. (Ferryboats, Metro trains, trams and your feet are much cheaper, and they move even when the street traffic doesn’t.)
