My wife and I and four friends took the Viking Grand European River Cruise and ALL SIX RATED IT A 10 OUT 10....it was fantastic!
Viking had made our airline reservations and our room was ready when we arrived at the Viking Vili Cruise Ship. The ship was almost new (it had only made three trips prior to ours) so it was clean and comfortable. Anyone that has taken a cruise knows the rooms are small, and there were also, but it was well planned and all space utilized. Even though we had three suitcases and two CPAP machines, we had plenty of room for the luggage and all of our clothing.
The excursions were well planned with clear, English speaking tour guides. Each city and country we visited was beautiful (I took over 1,800 photos this trip!). The food was excellent as was the service on the ship. The crew was excellent and our Program Director was superior!
