Well, I have been to Croatia 6 times I think but out of that, we were 3 times in the same area pretty much (in and around Sibenik) :D The other 3 stays were, as far as I remember, in Hvar, Primosten and Pula? No really sure. But Croatia is a spectacular country, you won´t regret visiting any place there I think. The Plitvicka Lakes National Park is truly breathtaking but it is usually packed with tourists...
