I had a fabulous time on Avalon's Jewish Heritage cruise on the Danube River. Despite the low water levels, we were able to keep our itinerary intact and made all the planned stops. Avalon does a Jewish heritage cruise once a year. Most stops focused on the history of Jews in the area, and the guides showed us former and current synagogues, monuments, and Solpersteine or stumbling stones, which commemorate the last residence of Nazi victims (https://en.wikipedia.org/wiki/Stolperstein).
The cruise director and local tour guides were very knowledgeable and friendly. The crew took great care of us. I especially liked be greated with wet washcloths and fruit-infused water when returning from excursions.
The dining room featured local food specialties each day, such as pretzels and beer cheese soup when we were in Germany, and fried Langos the evening of our day in Budapest. And the homemade ice cream daily was to die for! Coffee drinks like macchiatos and cappuccinos, as well as tea and flavored waters were available 24/7 in the lounge.
