ROFL!
Nope, never found the Monastery. But, I did see some parts of Croatia (and a bit of Bosnia) that was literally off the beaten track.
That';s what I like about renting cars overseas; seeing places that aren't "touristy". Rome was hectic, but as always there the main problem was finding parking. I ended up parking at the baths of Caracala (ruins of ancient baths that stretched over about 30 acres, well worth seeing!) , where there was plenty.
In many of the hill towns, etc, you park outside and walk in.
I've traveled by train and other public means before, but I keep coming back to driving; you see so much more, and actually save money (especially if not traveling alone): The hotels, etc, that are in the city centers (where you'll usually be stuck becuase that's where the train station is) charge a premium for being near public transport. Same goes for resturants in many places. So, with a car, you can get away from the cities and it doesn't actually cost any more in the long run, and it is a heck of a lot more fun.
