If the weather is good, I would do it again. We were there in about 2008, so it has been a long time, but I think the road was more potholed than it appears from photos now. Drove from Kotor to Centinje for an afternoon visit. It's the former royal capital of Montenegro, so a quiet place with historical buildings such as former embassies, and a trace of historical elegance remains. And the views from the road back down to the Bay of Kotor are spectacular. Yes, the road is narrow, but I recall it was about the same level of challenge as some driving we have done in Ireland and Barbados on narrow roads. Have some photos somewhere, I'll see if I can find them.
