We are considering a Viking River cruise of Paris and Normandy this spring. We have heard that the average age of the passengers is 60's to 70's. We would be the youngest people on the cruise. Also we understand that many of the excursions are bus tours only and not detailed walking tours. Meals are three times a day with no other food available on-board. We are interested in a river cruise and in seeing Paris. Is there any better cruise line for this?
I have done two cruises with Viking, and I'll be 30 next year. Our first trip was the South of France on the Rhone and Saone. Average age of travelers that cruise was 60's and 70's, but still active. The tours were small group walking tours of the cities, I don't remember any bus tours, save for one to get to Beaune, but then it was walking when we were there. Lots of fun!
The second was from Budapest to Nuremburg. The age of the passengers was much younger on this cruise, with even a few honeymooners. Same thing with tours, just small group walking tours. I usually chose to do the walk in the morning, then be on my own the rest of the day.
We saw other river cruise boats, and most of them seemed to be the same age range. Meals are three times a day with no other buffets, but if you go into the cities while you are docked, then you can go to cafe's and other restaurants. You'll be in France, so those places abound!
Overall, I would recommend them. That said, Paris is such a beautiful city, I personally do not think it needs to be on a guided tour. PM me if you want more info on river cruises or sea cruises in Europe.
