Not so expensive, a lot less than Italy
. Beautiful and crowded, specially on the central part. The main difference for most other med regions are the beautiful medieval villages that have survived.
If you don't like crowds go on May or June. The North and the South are more beautiful than the center and not as crowded. There are more people on the central Croatia
due to the main airports being there.
On the North you get more wind
Lots of places were you can stay for the night on the buoy of a restaurant on very nice coves and considering that, the meal is not that expensive.
