I booked the tour for me and my husband 2 days before, it was easy and quick and the confirmation came immediately. I would have only appreciated if it had been pointed out that the Dubrovnik Card holders should have already visited the City Walls to get the ticket to Fort Lovrijenac.
Like all Dubrovnik tours, our departed from the Pile Gate by the Amerling fountain. We found the manager almost immediately, and at 10 o'clock, even if we were the only 2 participants, we left for the tour in the company of our guide.
Marko is a big fan of Game of Thrones and he does is job with great passion. It's clear that he really loves both the show and his hometown: he told us many stories and many juicy trivia about both Game of Thrones and Dubrovnik, and we spent a wonderful morning in his company.
I recommend this tour, especially because compared to other similar rides allows you to sit on the iron throne: a very nice experience!
