Okay
Ferry and Drive to Mostar. 1 Night. (.5 day of sight seeing).
Im not a big fan of one night stands. 4 hour drive so you wont see much
Drive to Kotor. 2 Nights. 1 Day of sight seeing.
Im not a big fan of one night stands. another 4 hour drive
Drive back to Dubrovnik. 3 Nights. 2 Days of seeing.
and yet another day of driving followed by 3 nights in a 2 night town.
I think I mentioned in an earlier post that Kotor is sort of a waste after Dubrovnik (or before Dubrovnik). Perast is closer and its nice and different.
You could also maybe be a bit more efficient if you were to fly from Budapest to Podgorica and then get a guide to Kotor and to Dubrovnik (all in one day or with one night in Perast). Then rent your car in Dubrovnik and drive north to Lake Bled and go home from Zagreb or Ljubljana. Wizzair flies BUD to TGD non-stop on Tuesday and Saturday for $50 to $100 depending on luggage and the time of year.
