Budapest, Hungary

Your adventure starts after embarkation.

Budapest, Hungary

INCLUDED: Visit the covered market with the ship's chef, who will introduce you to local flavors and ingredients—like Hungary's most beloved spice, paprika. Later, take your pick of how to see the top sights in both Buda and Pest, either by motorcoach or on a guided bike ride. U TIME - COUNTRY SPARKLE: Head out to the Hungarian countryside to meet an aficionado of sparkling wines and enjoy a refreshing glass (or three) as he shares the secrets of making great bubbly. U TIME - HOUSE OF TERROR: This fascinating museum commemorates two bloody periods of Hungarian history and honors those held captive, tortured, and killed. An unforgettable look at fascism and communism in the 20th century.

Budapest, Hungary
Bratislava, Slovakia

Included: With its small town charm, Czech beer, Bohemian cuisine, and Art Deco cafés, the capital of Slovakia is well worth a visit—and you can cover just about everything on an insightful walk with your U host. U Time - River Wild: Just a short way from the city center, you can do something completely different—wild white water rafting on the Čunovo Canal with an expert guide.

Vienna, Austria

Included: Your first guided walk in Vienna provides an excellent overview of Austria's elegant and artistic capital, and also includes a tram ride about the city's famous Ringstraße (Ring Road). U Time - Operatic Cooking: Enjoy a taste of two classics—an intro to opera music and a Viennese cooking class. A fun opportunity to learn about arias and Apfelstrudel at the same time. U Time - Above Vienna: Vienna's giant Ferris wheel is the perfect place for a party in the sky—plush and roomy cabins where you can dine on street food and sparkling wine while enjoying incredible views over the city. U Time - After Hours: What's better than poking around a Baroque palace? Poking around after hours, when the crowds of tourists have all gone back home. Your guided tour of Schönbrunn Palace—the former summer residence of the imperial family—includes the state rooms and private apartments of Empress Maria Theresa. U Time - A Classical Evening: If there's one "must-do" in Vienna, the mecca of classical music, it's attending a Mozart and Strauss concert. After tonight's performance at Klosterneuburg Abbey, you can join the musicians and singers in the courtyard for a drink under the stars.

Dürnstein, Austria
Melk, Austria

INCLUDED: In the tiny village of Dürnstein, hike up to the castle ruins where Richard the Lionheart was once held for ransom—the views are amazing. Chill out onboard during a scenic cruise through the beautiful Wachau Valley, followed by free time in Melk. U TIME - TRAGIC AUSTRIA: Austria is so lovely that it's easy to forget its tragic history. You can learn more about that today with a guided tour of the Mauthausen Concentration Camp, which operated from 1938 to 1945. U TIME - SECRETS OF THE ABBEY: The Baroque-style Melk Abbey has a fascinating 900-year history and an extraordinarily beautiful library filled with priceless medieval manuscripts, optional illusions, cleverly concealed doors, and other intriguing secrets.

Linz, Austria
Passau, Germany

U Time - Deep Space: Venture into Deep Space 8K at the Ars Electronica Center in Linz, a unique and colorful visual journey through the universe that incorporates floor projection, laser tracking, 3-D animations, and projections at 8K resolution. Included: Explore Passau, taking in its Baroque cathedral and labyrinth of narrow crooked lanes.

Passau, Germany
Straubing, Germany

Included: Enjoy some time on your own today to look around Straubing. U Time - Beer and Meat: Treat yourself to a Bavarian cuisine and culture walk, visiting a craft beer brewery and a shop specializing in Bavarian meats. Meet a master brewer and a Bavarian butcher, sample beer served in champagne-style bottles, and learn how to pair charcuterie with craft beers. U Time - Into The Woods: Kick back on a scenic drive deep into the heart of the Bavarian Forest, where you can opt for a ranger-led hike or a mountain bike tour.

Regensburg, Germany

Included: Explore Regensburg's Old Town.
