First of all dont go….its’ rubbish. You’d really hate it…
In reality, its great and we love the place. Just come back last week from 10 days in Rovinj (ooop north). Stayed at the Hotel Lone which is right on the coast and next to (literally) Zlatni forest, which is ideal for cycling, running and nice walks. Weather was pleasant, 32c for the first few days then cooled down to 28c!
Rovinj itself is pretty, lots to see and do, as is the immediate area; hire a car if you can and explore. Lots to see and do.
We have in the past been to Dubrovnik twice and also visited Hvar,Korcula, Miljet (national park = amazing) and Sipan.
People all very friendly and helpful. Whilst Croatia is in the EU it is not in the Euro currency (for now). We found it pretty cheap to get by for food and drink and so on. A meal for two with starters and a couple of drinks is around £25.00.
Find a local supermarket and food is cheap in there too if you’re going self catering etc. Wine is expensive though!
Besides that a lovely place, great countryside, mix of people, ages, cultures and lots to see and do.
I’d recommend Dubrovnik for a mix of city break and beach and explore but also Rovinj.
Get out there, but don’t tell too many people what it’s like eh….
