River cruise ships carry around 90+ passengers, nowhere near as many as a sea going cruise ship able to accommodate thousands, so it is a more personal experience, but naturally with fewer social areas, amenities and entertainments on board. You are also close to land at all times so there are no days of endless sea vistas, no waves and no chance of feeling sea-sick. All the suites are outward facing, some with very spacious penthouse-style balconies, and all provide quality fittings and furnishings. There are many grades of luxury, however, according to the cruise company you choose. River ships stop along their routes for daily excursions and offer plenty of free-time as well guided tours.
