the girls are TALL. they also have bad attitudes. it's still better than the west though. you'll definitely need to speak croatian though to get past the sex tourist filter. you might think this is stating the obvious, but most people, like you, give up before they even try. if you speak polish you will understand more than half of croatian even as a complete beginner.
you avoid being sad and lonely by speaking croatian. or you could gather with a bunch of lads from a hostel. they are generally fun.
