I am Swedish and I have never been to Croatia and recently I have friends who will join me for a roadtrip to Croatia and they are not all swedish. My GF is chinese and she has a schengen visa but I travelled with her to spain with car and never had the hassle of border control. She is paranoid of control as she was kept in USA at Border for 4 days because she is a muslim -chinese. I will avoid croatia if it is still so strict on check ups after the entered the schengen
thanks Fabian
