While ships vary from cruise line to cruise line, almost every riverboat cabin has outside views. In Europe, choose between smaller, more intimate barges and larger more modern riverboats. European riverboats tend to be narrower, longer and sleeker, with lower-deck cabins being at or just above river’s view. These cabins range from porthole windows to full-size windows that span the width of the cabin. Mid- and upper-deck cabins feature large, panoramic windows at a minimum with some cabins featuring small balconies. For some cruise lines, every cabin has a smaller French balcony or full balcony.
