Maria Theresa is a luxurious floating palace that unites historic artwork and antiques with modern amenities. Unrivaled in its grandeur, this "six-star" river cruise ship has been inspired by the Archduchess of Austria, Empress of the Holy Roman Empire, Maria Theresa. A masterpiece of design, the vessel boasts 10-foot-high paintings, Venetian Murano glass chandeliers, hand-painted coronets with 22-carat gold leaf, silk-clad walls, lavish window treatments, custom furniture and five large murals depicting the 18th-century Austrian countryside. All this is combined with contemporary features such as TVs hidden behind mirrors, heated bathroom floors, climate-controls, WiFi and keyboards in each cabin. Maria Theresa can accommodate up to 75 passengers and offers an all-inclusive package, including meals and beverages (with the exception of top-shelf liquor), airport transfers, gratuities and most excursions. Passengers can expect attentive service, fine dining and wines that rival top restaurants ashore. The luxurious atmosphere and refined boutique experience is perfect for well-traveled cruisers in the 50-plus age range, particularly those looking for a touch of Downton Abbey-style grandeur. While the dress code is relaxed during the day, passengers tend to dress up in the evening, particularly for the captain's welcome and farewell dinners.
