Anyone ever been? I'm going there for a week on Monday. We're going to spend three nights there and then head out to one of the islands for another 3 nights, before spending the last night in Dubrovnik again. I've looked it up and I'd like to the cable car up the mountain thingy, walk the city walls, do some watersports like sea kayaking or preferrably jet skiing and go to the bar that's built into the mountain. Is there anything that is must see/do while I'm there or anything that people here would advise on seeing or doing?
