It’s natural to lose yourself in Dubrovnik’s fortified Old City, a charming maze of marble streets and terracotta-roofed buildings. UNESCO has recognized it as a World Heritage site, and HBO chose Dubrovnik as the stand-in for Kings Landing in hit show “Game of Thrones.” But there are compelling reasons to venture beyond its walkable historic walls. With Regent Seven Seas Cruises®, you can go cycling in the surrounding countryside, past old mills and vineyards, or take to the sparkling Adriatic Sea in a kayak, with a break to swim in secluded caves. Dubrovnik is a featured stop on many sailings, including the new “Old World Empires” itinerary from Jerusalem to Venice. And if you want to enjoy a bit of the royal treatment yourself, Regent Seven Seas Cruises makes Business Class accessible with its specially priced airfare upgrade option—or free, if you book a Penthouse suite or higher.
