We chose Avalon because of the service, bed facing window, 7 ft wide "room balcony" (Panorama Suite) and itinerary. The ports were altered due to the low water...but Avalon made it seemless by re positioning the ship to a better port in Austria (Englehartszell) with easy access to promised stops of Regensburg, Germany and Passau, Germany by luxury motorcoach. Avalon was kind enough to reimburse every passenger for the Vienna concert due to the slight change in itinerary and also offer a free traditional German lunch in Regensburg, Germany. All in all.....Avalon made the entire change easy on all passengers and presented an incredible cruse with relaxing and easy on and off stops along with delicious meals which included complimentary wines and beers. The crew and staff were amazing especially our cruise director Marie who was available almost 24/7. The Captain was very personable.....allowing access to the bridge during sailing times and explanations of the ships operations.
