2 weeks in Croatia in June. Too little time?

I'm wanting to take advantage of Juneteenth and 4th of July weekend for a 2 week trip somewhere. I'm kind of set on Croatia because I've never been and thought a coastal destination in Europe in June sounded appealing. Is 2 weeks enough? Should I squeeze in Montenegro? I was thinking Dubrovnik > Split > Hvar > Kotor in no particular order. Seems like from Florida getting to and from Dubrovnik is the easiest route. I'm not a budget traveler (although ideally don't want to pay a ton for flights) and it's definitely not the cheapest option but it seems like it'd be nice to visit. Anything I should be considering and is a baseline itinerary doable or am I doing too much? Thanks!
