I'm trying to plan a trip for the first or second week in May to Dubrovnik. it will be our (my partner and I) first time in Croatia so we want to make the most of our time but not overdo it that we feel rushed particularly as if we enjoy this trip we are hoping to come back in the future and explore more of the country. We are probably going to go for 4/5 nights depending on flights but could really do with some help regarding the itinerary.
We know we want to explore the old town but beyond that we are unsure what will be open/running and in reach of where we are. We hadn't planned on hiring a car (but could do so if it's worth having one) so were planning to make use of buses and ferries. Although from looking into the ferries am I right in thinking most of them won't start running until the end of May/early June? In which case are we going to be rather restricted in what we can and can't do for day trips?
I've also read mix reports that the water may be quite cold still in early May and not great for swimming but do you think it will be okay and are there any areas near Dubrovnik for swimming?
Any help, advise or ideas would be greatly appreciated as planning this trip is proving harder than first though.
