We hear the question, "What’s the next Prague?" a lot. But while we’re all for discovering great new destinations, we hardly think Prague is over. Sure, everyone’s heard of it, but it’s still a grand city with extraordinary historic and cultural sights, and it’s definitely worth a visit. The often-rebuilt Prague Castle has overlooked the city since the 9th century, and the synagogues and cemetery of the Jewish Quarter are must-sees. Nightlife here is diverse and plentiful, from trendy clubs to sophisticated wine bars to late-night cellar bars.

Edinburgh is Scotland’s capital city, renowned for its heritage, culture and festivals. Take a long walk around the centre to explore the World Heritage Sites of the Old Town and New Town, as well as all the area’s museums and galleries. Then stop for a delicious meal made from fresh Scottish produce before heading out to take in one of Edinburgh’s many events — including the famous summer festivals of culture, or the Winter Festivals of music, light and ceilidhs.

During the Civil War, Knoxville's Mabry-Hazen House served as headquarters for both the Confederate and Union armies. Today you can visit the house and other historic homes in this eastern Tennessee city. Among Knoxville's other attractions are museums, a zoo and the park that housed the 1982 World's Fair. University of Tennessee sports draw lots of fans, as does the Women's Basketball Hall of Fame. To see Knoxville from the water, take a leisurely riverboat ride down the Tennessee River.
