I have already booked our flight but I am hoping we are not too crazy with this and also looking for some advice in the istrian region.
Fly into Zagreb and spend the night
Drive to Sarajevo and spend 1 night (want to go through Doboj where my grandmother was from)
Mostar - 1 night
Dubrovnik - 3 nights (thought a break, relaxation would be great, maybe a day trip from here?)
Split - 1 night
Plitvice Lakes - 1 night
Postojna - 2 nights (truffles - caving - castles)
Lake Bled - 1 night
Zagreb - 1 night before flying home
We actually have 2 more nights to spend but don't know where, I know Venice is not far away but should we focus on istria more and its coastline?
