148-passenger Amabella debuted in May 2010. She is the first of APT's new Concerto class of River Ships.

Here's what you can expect on an Amabella cruise:

The line offers nearly all-inclusive cruising. Beyond the cruise ship standards -- food, accommodation, entertainment -- there's wine and beer with dinner, unlimited Internet use and guided tours in each port. There are also about 20 bikes available for exploring onshore (no additional fee).

Standard cabins are 170 square feet, a decent size for a river cruise industry where cabins are typically in the 150-square-ft. range. All cabins have "Infotainment" setups, basically flat-screen TVs with Internet access, movie and music libraries, bow and navigational cams and more. 82 percent of cabins feature a French balcony, a sliding glass door with railing. Cabins on the lower Piano deck feature picture windows right at the water line instead of French balconies.

There are two lounges on Amabella -- a large main lounge at the bow and a more intimate lounge located aft -- that offer panoramic views of Europe, as well as a sun deck with whirlpool. Other onboard amenities include an elevator, small fitness area and a treatment room.
