Question Montenegro and Albania Itinerary Help

Our family of five is considering a trip to Montenegro and Albania next summer, flying in and out of Dubrovnik. We’re particularly excited about visiting Dubrovnik, Kotor, Durmitor National Park, and the Accursed Mountains. I’d love some advice on how to best structure our itinerary. What's the ideal amount of time to spend in each location? Are there any must-see spots or activities we shouldn't miss? And how about transportation between these places? Any tips would be super helpful!
