Schengen visa and Croatia trip
I have a Schengen visa from Spain. Plans have changed and thus I cancelled my trip to Spain and I will be traveling with my friends to Croatia and Montenegro which are not yet part of the Schengen zone but they admit tourists holding Schengen visa. However my concern is whether not having a stamp on my passport from Spain or any other Shengen country could negatively affect my future visa applications to Shengen countries (Spain and others...).
Appreciate your feedback.
