Tour begins: 5:30 PM, Fairmont Golden Prague Hotel. A transfer is included from Václav Havel Airport Prague or the Praha Hlavni Nadrazi train station to the Fairmont Golden Prague Hotel in the heart of the city. Begin your amazing Blue Danube river cruise adventure early this evening with a Tauck Exclusive – a royal welcoming reception, tour and dinner at 16th-century Lobkowicz Palace at Prague Castle. Immerse in an evening of classical cultural treasures – music and art played an important role in the aristocratic world of the Lobkowicz family.

Start today's exploration of Prague this morning with a choice of walking tours through Prague's ethereal Old Town, choosing between a one-hour introductory tour; a "walk through the centuries" (note: this excursion has two versions, with one being shorter and less requiring less walking); or the city's poignant Jewish sites in Josefov, the historic Jewish Quarter (ask at booking about dates that cannot visit inside the Jewish Heritage sites as they are closed Saturdays and on Jewish holidays; in those cases, alternate sightseeing will be offered). This afternoon, your choices in the ancient Hradcany (Castle) district include the 1,000-year-old Prague Castle's complex of palaces, courtyards and gardens; the magnificent Gothic Cathedral of St. Vitus; and the grand Baroque libraries of Strahov Monastery, where a private tour is a Tauck Exclusive. Sample the culinary pleasures of Prague on a free night to spend as you wish; the city's many fine restaurants and cafés feature a wide range of cuisines... and some of the best schnitzels, goulashes, strudels, dumplings and beer the region has to offer. Tomorrow – your Danube river cruise begins.

Depart this morning for the town of Regensburg for a walking tour nad lunch on your own. This afternoon, drive to Germany, where you'll board your riverboat and launch your 7-night Danube cruise. Join your shipmates and crew at a welcome reception followed by dinner aboard the riverboat tonight.

Take in the views from your riverboat's sun deck, lounge, or the windows of your outside cabin as your ship glides along the mighty Danube this morning. Your first port of call on your cruise is Engelhartszell, a pretty town on the Danube in Upper Austria. After a visit to a local private home (and a taste of local cake, sweets and coffee), you'll have a choice of a walking tour of town including 18th-century Engelhartszell Abbey and Danube Welt, or a visit to a local art museum. Following lunch aboard the riverboat, you may, if you wish, join us for an optional bicycle excursion along the Danube to Aschach (a fairly rigorous bike ride, for experienced cyclists only) before continuing your cruise this afternoon, bound for Linz. Enjoy the Chef's signature dinner this evening; after the riverboat's arrival in Linz, the musical trio Donau3Klang entertains onboard tonight.

Your boat stays docked in Linz today, with a choice of how you spend your day – full-day excursions to Salzburg (Austria), Cesky Krumlov in the Czech Republic, or remaining in Linz. A setting for The Sound of Music, Salzburg is enticing with Baroque architecture, painted wrought-iron signage, ornate church towers, and grand palaces. Our walking tour explores Old Town, Mirabell Gardens, and Mozart's birthplace with time on your own to have lunch and experience the sights as you wish. Alternatively, travel with us through beautiful landscapes to Cesky Krumlov, which has been called a living gallery of elegant Renaissance-era buildings with a well-preserved medieval heritage and charming ambiance. A walking tour takes you to part of Krumlov Castle; it's worth climbing the many steps to see firsthand the medieval, Renaissance and Rococo design found inside, along with the stunning views of the town below. Your riverboat overnights in Linz.

Dock in Dürnstein for a closer look at its 16th-century Baroque houses and 13th-century Romanesque church on a walking tour along cobblestone streets; or join us for a bicycle ride in the Wachau Valley. If you wish, visit the Augustinian Monastery. Enjoy some free time in this charming riverside town – perhaps taking an invigorating climb up the steps to the ruins of Kuenringerburg, a hilltop castle above the town where Richard the Lionhearted was held for ransom during the Crusades, from which the views of the river and valley are glorious – and sample the fruits of the Wachau Valley vineyards during a wine tasting at an authentic Austrian tavern. The riverboat departs early evening for Vienna.

Your riverboat arrives overnight in Vienna, Austria, where an introductory tour of this former capital of the old Habsburg Empire – and its grand boulevard, the Ringstrasse – precedes a walking tour focusing on medieval Vienna and complimented with various samples of the local cuisine. Alternatively, enjoy a more active walking tour that concludes at the Albertina. The afternoon is yours to explore this famous city as you please. Later, nothing compares to the royal treatment and pageantry you'll experience tonight at our private Imperial Evening in the Palais Pallavicini, an opulent, private Viennese palace that played a role in the 1940s film noir classic The Third Man. Welcome cocktails and dinner precede an unforgettable spectacle of beautiful ball gowns and a musical performance celebrating the legacy of Mozart.

A choice of sightseeing this morning features either a tour of contemporary Vienna, or a visit to the Kunsthistorisches Museum Wien, one of the world's most acclaimed art museums located in a palatial building on the historic Ringstrasse.

Back aboard ship, get ready to celebrate tomorrow's arrival in Budapest.
