Thanks for the comments! Photobucket is back on, and a slideshow selected from the film rolls should now be available in this link
The dome is described in tourist brochures as a "defensive structure". Locals call it "the Pile". All around the dome there is a fountain, with water flowing from faucets all the time. Water is cool and drinkable, so in 31 C weather people refill their water bottles and sit around after negotiating the stairs. All of Dubrovnik is stairs, many "streets" in the map are actually stairs. Good exercise.
I have not watched Game of Thrones but my kids tell me that several parts of Dubrovnik old city were featured in the series.
The two film cameras did their job well. Nothing beats a XA for travel, and the lens in the Super-Isolette is superb. I had thought of bringing a SLR with 24mm or shorter, but after all it is travel with the family, not an assignment. This area would deserve the full Nikon set, a good TLR and tripods; but then I would have needed an assistant and much more time than we had, not to speak of 20+ less years of age. However I did see several dedicated amateurs (or maybe they were pros) setting up their tripods and equipment, looking for the best composition or angle, and generally behaving like photographers.
I saw some film being used as well. A few people with Prakticas around, even one with a Fed 3. In the digital side, quite a few with mirrorless high-end digital cameras, and some DSLRs, almost no P&S. The crowd - selfies with their cell phones.
Got to a good photo store in Budapest and brought home some TMX in 120 as a souvenir.
Not too much trouble with X-ray machines, which are much discussed in forums. My film went through at least 8 machines for hand lugagge and came out OK.
