This splendidly elegant ship cruises along the Danube River boasting ultra-luxurious accommodations fit for Empress Maria Theresa herself. As a tribute to the only female ruler in the House of Habsburg, a 10-foot-tall, specially commissioned portrait namesake hangs in the two-story foyer. Travel like royalty surrounded by opulent silk-clad walls, a Murano glass chandelier in the lobby, eye-catching patterns in every room, handpainted coronets and a mosaic-tiled enclosed swimming pool.
