AMAWaterways, Avalon, Uniworld, and Viking River Cruises are the top players in river cruising. Tauck is also a player in the luxury category and has their own ships. They all include shore excursions of some type. Most of them are walking tours. As mentioned, if you don't want to participate just let the guide know so they aren't waiting. In Europe there are a lot of cobblestone streets, uneven payment, and inclines.
