Thank you for the info Mister E. Is it difficult to find parking in the towns along the Montenegro Bay? I'm wondering if we should do this as a day trip from Dubrovnik or whether we should spend one less night in Dubrovnik and rent a car and do this trip on our own with an overnight in Herceg Novi or Perast. We would continue on from the Montenegro area to Mostar before heading to Split.
A lot of Herceg Novi is pedestrian so you will have to find a place to park and walk.
Last time I was in Perast, about 18 months ago, we had to park at the outskirts and ride a golf cart in.
Kotor has parking outside the gate to the old town.
If you wanted to spend the night, my pick would be Perast. i first stayed here about 10 years ago, and liked it enough where I keep returning to it. Love the restaurant in front on the edge of the bay too. But there are a number of very nice places to stay. https://hotelconte.me/
Rent a car if that makes you most comfortable, but other than getting from point A to point B it won't serve a lot of purpose. This really is a good trip for a driver and a better trip with a guide; and Montenegro guides are cheap and will get you in Dubrovnik; and return you to the airport if that's what you want.
One of my favorite little facts: Montenegro is not in the EuroZone. The currency in Montenegro is the ..... well ..... the Euro, They basically said, we are going to use it whether you like it or not and the EU just sort of kept their mouth shut.
But another troubled country thanks to outside influences; and a country with the possibility of something really ugly happening some day. But my G-d its beautiful. Look up Ostrog Monastery and the cafe at the Hotel Sokoline. The food is good, but all you will remember is the view. You can cover a lot of it in a few days with planning and transportation.
