I cringe at the thought of even asking this since I hate organized tours, but does anyone have any stellar recommendations on an organized big (or mini) bus trip to Mostar from Dubrovnik? What I'm looking for is something that would give us the most time in Mostar with a minimum of other stuff, ie not stopping at that GREAT souvenir shop on the side of the road that pays the driver/tour operator commissions.
We used guide Petar Vlasic to drive us from Dubrovnik to Mostar for the day. He was fantastic. He picked us up and drove us to Mostar. He stopped at a small mosque along the way that was interesting to check out. He brought us a bag of the awesome green oranges to eat along the way, he drove safely in his black BMW, and he shared the history of the Croat/Serb fighting with us from the perspective on someone living in Dubrovnik at the time. He was absolutely awesome. I believe we paid $250 for both of us for a full 9 hour tour. It was just the two of us, driving around with Petar....a truly spectacular day. This is his email: email@example.com
We took a minibus tour with Super Tours. It was okay, but not "stellar." Our trip had a stop at Međugorje which we didn't really care for. The church was modern and the rest of the town was souvenirs. If you are a devout Catholic, Međugorje would be more interesting. We went on to Mostar and had a few hours there. We also had a short stop at Počitelj on the return trip which I enjoyed.
I don't know of a tour group that just goes to Mostar with no other stops. Your best bet may be to find a private guide. Check out Rick's book on Croatia for his suggestions.
