While visiting Dubrovnik and the islands, you are certainly better off without a car; parking is hard to find and very expensive, and the bus system is great. If you must bring a car into Dubrovnik, there is a public parking garage at Ilijina Glavica on Zagrebačka street leading to the Old Town, where you'll find the most reasonable prices and space. You may want to rent a car for a day or two if you are traveling up the coast to the Pelješac Peninsula or down the coast to Konavle, as these areas are not well served by public transport.
