It seems many on this forum have rented cars for driving the length of the Croatian coast. I am planning to do this in May. Then I saw this recent response to a post:
We have found that car hire companies have not permitted us to take the hire car into Bosnia (Mostar) when renting from Split airport so you will need to check the rental terms or pay extra to get covered for Bosnia. Most hire companies also will not permit the car to be driven through the narrow coastal strip of Bosnia to get to Dubrovnik.
Please advise. I am planning to drive from Dubrovnik to Mostar, Mostar to Split, and beyond into Slovenia. I plan to tell them ahead of time (rental company) and am okay with paying extra fees.
Thanks in advance,
