We just finished a Viking Cruise from Budapest to Regensburg on the Jarl. We were able to board in Budapest on Oct 29 near the Chain Bridge and ended docked in the center of Regensburg! Made all our stops and had an amazing time. There was a little rain in Vienna and Passau but otherwise great weather. We hope the rest of their season goes as well.
Already planning for the Douro River in the spring.
