For Mature Adults. We wanted to see more of Europe. Viking was the best Choice. Cruise Staff was highly knowledgeable and friendly. Chef served fantastic meals. Tour Guides brought in a lot of area insight. Tours were great. We got to see and tour Castles, Museums, and Market Places. We took the Pre-tour to Munich and Salzburg (Sound of Music Tour.) It was Fantastic. Going inside Castles was a true delight. The Food Menus changed every day, their was plenty to eat and savor new dishes. We never had the same food twice. Everytime we came across a Cruise Staff member, they always asked, "Are you having a good time? I s there anything that I can get for You?" If there was anything that was not working properly, someone came right away to fix the problem. We will be planning our next trip, and it Will be Viking Cruise Lines.
