I am arriving in a cruise ship with my wife during the end of October. I am planning to walk around downtown, Konak, the Clock tower, the Agora, Kadifekale and up to Asansor. My first and most important question is if it is possible to take public buses paying the trip in cash and avoiding the use of a Kent Kart (maybe we will use only one or two rides at the most). As far as I have seen, the price is 1,75TL. Thanks.
