Hi! We are five adults planning a 1-week car trip around Slovenia and Croatia (last week of May). We will arrive to Ljubljana, pick up a rental car, and we have to get back to Ljubljana to go home, so we will drop the car there again.
I've come up with two plans which basically involve choosing between Istria or the Split area. We don't have time to see both.
The general plans are: (8 nights in all)
Plan A.
Stay two nights in Ljublana (see around Julian Alps). Then drive through Karst to Istria, and sleep two nights in Rovinj (see around, Rovinj, Pula). Then drive along the coast and sleep somewhere around Crikvenica/Senj (where? recommendations here?). From here go to Plitvice Lakes Nat Park, sleep two nights in Plitvice. Drive back to Ljubljana, sleep last night there, go back home next morning.
OR
Plan B. Instead of going to Istria go to Split and stay two nights there (with the one night around Crikvenica/Senj before these two). Then go to Plitvice/Ljubljana, as above.
Can you please give us some advise to help make this choice? Istria vs Split? Why? Many thanks!
