My wife & I will be in Zagreb the first week in May, 2016. Our stay there will be at the end of a near two-week trip that involves almost a week in Dubrovnik. From there, we will be winding our way to Zagreb before flying home (to New York) from there.
The question here is: how much time should be given to Zagreb? We will be driving from points south and dropping our rental car off at the airport. We can plan one or two full days there (i.e., two or three nights). How much is there to see? Is a full day sufficient?
