My wife and I booked the Viking river cruise in Europe for our 25th wedding anniversary and it turned out to be a bus tour of Europe!
The river level was too high for the first four days so we couldn't leave Basel. Finally the river level went down slightly and we began moving. Yippee!
Oops, we only went about thirty miles then found out that the lock workers were on strike so we couldn't pass through the locks. Dead in the water... More bus tours... So we didn't get the experience of the river cruise, didn't get to use our balcony that we paid extra for.
