My wife and I have done two other river cruises, one on Amawaterways and one on Viking. The Crystal Mahler is a new ship the same size as all the others but only carries 110 passengers and has 68 crew members. Everything is inclusive on the ship, gratuities, all bar drinks, excursions and one Michelin Restaurant dining experience.
The ship was launched in October and this was it's 4 cruise.
You are picked up at the airport and returned for your trip home.
The cabin is quite nice but the bath room is somewhat small since both of us are over 6 feet tall.
