Just back from Serbia/Bosnia/Croatia. All amazing places, in particular Mostar and Sarajevo in Bosnia. So much to see, sunny all the time, good food and pretty cheap to travel around and see. People were pretty friendly as well, so if anyone is going travelling around that area of the world, I strongly recommend it!
Only downside I had about Croatia was that it wasn't far off UK prices, well the areas which we visited anyway, but still, a nice country to go to
