I'm planning a bit over a month long trip and hoping to visit mostly Slovenia, Montenegro, Albania. The flights are cheap going into Rome, so we were going to spend some days there, rent a car, drive to Slovenia, visit, then spend a few days in Bosnia (of course would have to drive through Croatia for that) and then explore Montenegro, Albania, and finally take a ferry from Albania back to Italy.
I have heard this is very difficult with a rental car. I just looked into Hertz as an example (they had fairly cheap car rentals) and they do not allow their rentals to go into Bosnia Herzegovina, Montenegro, or Albania.
I understand I'd have to pay a tax to cross the boarder with the rental car, but that isn't an issue. I am wondering what rental companies may allow me to drive in these countries?
Unfortunately, Montenegro and Albania don't have the best public transportation (nor is there a very direct way to go from Slovenia to those countries). Also, I'm afraid it won't be easy to get to the small towns we're interested in exploring without a car.
Any ideas for companies that would allow us to pick up a car in Italy, return it to the same station, but allow us to drive in these countries?
