Not Viking. They are awesome, and no riffraff. Worth every penny.
But A LOT of pennies!
Except they wouldn't allow me to wear my horned helmet to raid and burn villages along their route. Viking indeed!
We did a river cruise with Viking about 10 years ago. Basel => Amersterdam.
We liked it quite well. The only down side is you’re a little locked into eating on the boat, not that the food was bad or anything, it was quite good. Just that eating at a local restaurant meant you were effectively paying twice for the meal.
