We have been on other river cruises with other vendors. We heard that Viking was the best and wanted to see Berlin and Poland so we thought we would give Viking a try. We agree it's the best although also the most expensive. The service and accommodations were the best. Our tour director and ship director were extremely organized, helpful and had a great sense of humor. We have already booked another cruise with Viking and are looking forward to it. The shore excursions were extremely well done. The local guides were informative, interesting, and professional. The only shore excursion that did not live up to our expectations was the Prague at Night we were disappointed that we didn't book the folk dinner instead. We also loved every aspect of the extended post tour of Poland, accommodations, excursions, etc.
A minor disappointment was the food, although abundant and the service outstanding, was not exceptional. The servers were very congenial and made us look forward to our next meal to be able to talk with them. Several other guests remarked that the other Viking ships food was much better.
