Amadeus River Cruises, an Austria-based company catering largely to European passengers, has worked to tap into the American market in recent years with its budget-priced cruises. The relatively low price includes extras, though, like complimentary wine with dinner (the cuisine is also a highlight). By the end of 2016, the line will operate a dozen ships sailing river itineraries in France, Germany, Hungary, Austria, the Netherlands, Slovakia, and Belgium, as well as Myanmar, Cambodia, and Vietnam.
