Beautiful, mile after mile on the winding coast just like California's Hwy One except the view is across to islands rather than empty sea.
Perfectly safe & clean, and attractive - tho time limited our visit to within about 40 miles of the Adriatic coast.
Not a wide choice of hotels, but lots of independently-run apartments and B&Bs - anywhere from just the one to half-a-dozen, usually attached to the owner's house and all run by friendly & helpful folk with pride in their hospitality.
Found the prices - from accommodation and car rental thro food to beers and ice-creams - broadly in line with the US. Inexpensive in most places, expensive in touristy places like Dubrovnik and Split.
BTW, Hank, do check whether you can take an Italian rental car to places like Croatia, Slovenia and Montenegro.
I've been told that most rental agencies in Italy won't allow it.
And it's expensive to take a Croatian rental car into neighbouring countries, other than the 5 or 6 miles of Bosnia's coastline on Hwy 8 which links the two halves of Croatia.
