The Library: On all river ships, space is limited due to the fact the ship has to fit into locks and under low bridges. But on its Suite Ships, Avalon makes the most of what it's got — including in this delightful, windowed room with a self-service espresso machine and views facing aft.
The Inclusions: Daily tours are included in the cruise fare (additional options are available for a fee), and so is sparkling wine with breakfast and beer and decent (and sometimes local) wine with lunch and dinner.
Fireplaces: It's a gimmick, but when you arrive back in your cabin at night, there's a roaring fire and classical music on the flat-screen TV. It's oddly soothing, even a little sexy.
