I was in Croatia a month ago, lovely scenery. I did go to Dubrovnik, and it made my head spin,. In fairness it was only a 20 minute bus ride from where i was staying, so worth a punt. Certainly not my cup of tea, but each to their own.
I did find Croatia was quite expensive compared to other places, but the scenery more than, made up for that. And we did fall lucky with the weather, so that helped.
