We ( my husband and I ) are going to be in Croatia and Slovenia next May. Figuring out where to stay over just 5 nights in Slovenia after 21 days in Croatia as doing bike/ sail trip etc. Want to see the caves like Skocjan and Predjama castle , Ljubljana, Lake Bled and Bohinj, Julian pass and soca Valley.
Figure do caves and castle on a Thursday on way from Rovinj in Istria, to Ljubljana. Then spend 3 nights (Thursday, Friday, Saturday) in Ljubljana, Will need to figure out place to stay here, might try an apartment but need parking as will have car.
See Lake Bled Sunday, stay one night (Sunday) in this area not necessarily Lake Bled itself. Then drive pass and spend one night in that area such as Kobarid or possibly Triglav Park area. (Monday night) Or just base ourselves for 2 nights in Lake Bled and play it by the weather conditions whether Vrsic Pass doable. Car will not have snow tires as renting from Split and dropping off in Zagreb. . This would be last week of May. So not sure if driving in mountains even feasible. We need to be in Zagreb for Tuesday night May 29th as flying home May 31 st from there.
