Vonnegutnut and purplekedi know what they’re talking about. No need to repeat the same stuff over and over again.

Just a slight thing; what do you describe as fun?

A recklessly getting thrashed type of a fun (where you wake up the next day and don’t remember anything else but you had a lot of fun); overdo what vonnegut says about istiklal. Drink and dance and pub crawl!

But if your description for fun includes enjoying Istanbul (by the means of food and culture) and having pictures in which you are actually looking at the camera (or can look at the camera), than go for purple kedi’s advices.

Have a fun trip (by your descriptions of course)
