I assume many of you, like me, have received mountains of advertising about Viking River Cruises. If you have any interest, here are my thoughts after completing the "10-day" cruise from Amsterdam to Basel, Switzerland, via the Rhine River. (1) There are mainly geezers on board, FWIW. The going is often slow on walking tours, getting into the bus, and so on. But you are on vacation, so lighten up. (2) The cost varies greatly, depending on when and how you book. So if you are interested, be creative in your approach. The best deal we heard about was a couple who booked a couple weeks in advance. We booked 6 months in advance and obtained a theoretical 50% savings, but just about everyone we talked to paid pretty much the same amount, so I don't think anyone actually pays the published standard rates. And remember, Viking wants all your money very early in the process, so if you do it the normal way, they will be holding your money for several months before you actually embark. (3) All the "infrastructure" is great. Boat is excellent, clean, modern, and fully equipped (they are all basically the same design and size, due to constraints of the river locks and dams). Food and service are excellent. Transport is flawless. Seating at meals is "open," so you are free to make friends and either sit with them regularly or move around to meet other people. With only 180 people on board, you can meet a lot of people in a relatively short time. (4) Hold on to your wallet. They are constantly grabbing at it for one thing or another. There is an included tour at every port, and their tour guides are excellent, but they are always at you to buy the Optional Tours, which are god-awful expensive. Drinks are, of course, over-priced, but not as bad as at a baseball game, so I guess it's all right. (5) There is not as much going on in the boat as on an ocean cruise. No casino or shopping mall on board, no "Broadway" or "Vegas" shows to see on the boat. Remember, on an ocean cruise, 70% of the motivation is the Ship, and on a river cruise, 70% of the motivation is the destinations. (6) Our stops were fantastic. The cities and towns and things we visited were great, and well worth the price. The tourguides were excellent, but they all speak with an accent, and you will have to give them 100% attention to hear and understand everything they are saying. Viking also provided some short on-board lectures on what it is actually like to live in Germany and Switzerland - I thought these were as valuable and informative as the tours themselves. This is a great way to see some fabulous, interesting, important, historical venues. Doing it by rented car would probably be cheaper, but there is some value in not having to worry about finding places to stay and park, and getting acceptable food to drink. On the river cruise, there is an excellent meal, included in your fare, three times a day. if you want to eat "on the economy" you are free to do so, but having that fallback is good. (I gained about 5 pounds on the 14 total days of this trip). If I feel inspired later I will write some about the specific cities and castles that we visited, but those are specific to this tour. For now I just wanted to give my thoughts on river cruising with Viking in general. It's all about value for the money. We paid about $11,000 for ten days, including the airfare, and we probably got dinged for a thousand more in miscellaneous bullshit, including tips (a whole 'nother subject, if you know what I mean).
