After all of the help from this wonderful forum I think our itinerary is pretty much ready to go. As always, having a few more days would be nice, but I have done the best with the time we have. This itinerary is part of a 6 week trip, we arrive in Dubrovnik from Amsterdam and wont have any jet lag issues.
Day 1 - Arrive Dubrovnik 10am. Walking tour booked for 3pm.
Day 2 - Dubrovnik
Day 3 - Dubrovnik for morning, afternoon bus to Split
Day 4 - Split - 11am walking tour booked
Day 5 - Split, morning in Trojir (boat or bus there) - pick up car in late afternoon
Day 6 - Leave early - heading to Plitvice. Looking at visiting Sibenik on the way / maybe Krka National Park? Stay in Plitvice.
Day 7 - As early a start as we're allowed in Plitvice. (is it 7 or 8am they open? I keep reading different things) Mid afternoon, drive to Ljubljana
Day 8 - Ljubljana
Day 9 - Day trip to Lake Bled area
Day 10 - Possibly Julian Alps / explore area around Ljubljana - suggestions welcome!
Day 11 (a Sunday) - to Skojan Caves for 10am tour then to Lipica Stud Farm for 3pm performance. If time I would like to do a carriage ride and tour the stables too. Drive to Rovinj - approx 2 hour drive - debating this drive and might stay somewhere closer to Lipica, like Koper.
Day 12 - Rovinj / Motovun - day on this peninsula just to see a little of it - most likely stay in Koper and then the next morning get a train to Venice from Trieste.
We have booked accommodation in Dubrovnik and Split but nothing else yet. We could possibly add one more day to this itinerary. If you have any feedback, I would be really interested!
