We went on the AMA Danube river cruise last year, but not ABD. It was really fun, but really cold and pretty rainy. Be sure to bring long underwear, warm socks and very appropriate shoes. I did not think many people really dressed up for dinner like a normal cruise, which is good because you really need practical clothes to deal with the elements. They did provide umbrellas, but we still liked having our small foldable umbrellas. It is lots of fun, the crew is great, and the markets are so charming. They do get a bit repetitive after a while. You will have tons of goodies you purchase so I recommend an extra foldable bag and the bubble wrap is a great idea. I have an entire collection of mugs from all the markets and I just adore them. Have a great time, hope it goes.
