I am still of the very strong opinion it is too much and I am believe you don't have enough time to enjoy any of your towns. Trying to drive from Dubrovnik north and visit all the major sights can't be done well in one trip.
Do not assume that you will be making wonderful time on the roads. Driving can be confusing and sometimes you are kept at the Bosnian border for no reason.
If you are planing to walk and enjoy the beauty of Plitvice then perhaps you may need another night there, just to regroup.
Rather than stay in Split, do look at Trogir which is just a short drive into Split. Trogir is small and very special and such a better alternative to Split.
Again I must advise you, as a retired travel consultant of 30 years experience, it's too much. This itinerary reminds me of the wonderful movie which only a few of the Fodorites will remember: "If it's Tuesday It Must Be Belguim."

Dobrodosli u Dubrovnik

fishtrom - I do recall Economy Car Rentals showing the charge for the green card to cross the border. I can't remember how much it was, though. Perhaps the other rental companies just aren't showing you an itemized quote. You will have to show this card along with your passports at each border crossing so you will need it regardless of the rental company you choose. We had a great experience with Economy Rental Cars so I would definitely go with them if they are the cheapest.

Carol - I am so glad you enjoyed my report. I can't believe your cousin is the waitress at the little cafe where we stopped. Orebic seemed like it would a lovely place, and I'm sure it's even more enjoyable in the warmer weather. We do hope to make a return trip to Croatia in the near future. We saw a lot while we were there, but I know there is so much more to see and do.

nannibray - As you can see from our trip report, we also crammed in a lot during our short visit and we didn't regret it for one second. That said, I think 4 days in Dubrovnik is wise. Carol makes a great point that the drive to Montenegro is unpredicatable. We had a much longer wait at the border than we expected.

I would recommend sticking to one island for 2-3 nights. How are you planning to get to Korcula? The drive up the Peljesac Peninsula to Orebic was lovely, but I don't recall the best route from Mostar.

You could take the early morning ferry from Korcula to Split as we did. We didn't want to spend the night in Split so that worked well for us. I can't speak to the Slovenia part of your itinerary since we didn't venture there...yet!

Hope this info helps and happy planning!!
