We took the cruise from Koblenz to Bingen. The day we went was cloudy, but the views were still great almost as good as a Viking River Cruise commercial. The staff was pleasant and food service was good. Overall, we enjoyed the cruise and would do it again if we find ourselves in the region.

Travel Note: we had a Viator voucher which needed to be exchanged for a ticket. Although the voucher states an electronic version can be presented, the ticket agent really wanted a paper print-out. By accepting the electronic version, she was required to complete a form before she could give us the tickets.

May 2018 - Wonderful experience! The hop on/ hop off terminology is a bit misleading since you really need to look at the port schedules very closely. One boat travels up the Rhine and one travels down. Not all ports have convenient departure and return times. We ended up driving to the town of Rudesheim to have better departure times because Wiesbaden only had one departure time. Aside from the complexity of determining the departure time/place - the cruise was unbelievable! It was worth the trouble to se the beautiful castles and sites!

The Rhine River tour was Great. Awesome, Awesome. Only One Problem. 4 Boats and You Have No Clue Which One. Very Poor Instructions. I would rate the boat ride a 5. As far as the rest. I, was most Stressed. They get a Zero. We almost missed the boat.

The Viator voucher Rhine River 20 Castles.. was not what we expected. When we presented our voucher at Cologne, the ticket office clerk told us that to see the heritage section of the river, we would need to take a 2 hour train journey to Koblenz, presumably the nearest starting point for the 20 castles section of the river. Time did not allow this, so we took a day trip on the river. The Rhine that we saw was reasonably interesting, but not what we thought we had bought. We had only two seriously disappointing days on our 28 day Europe holiday, and this was one of them.

We really enjoyed this river cruise however, we made the mistake of going both ways. We would have preferred to travel only one way, especially since it was so cold when we were there in August. It is a spectacular cruise for seeing a lot of castles, and we had a great time at Boppard. It's a charming little town that we had never heard of until we arrived there.

It was difficult trying to figure out the time schedule, and missed the morning departure. We took a train to the turn around location and got on board and got to see the awesome views on the Rhine River!

My family and I went on this cruise last July. It was awesome - we really enjoyed it. The only question we had was that it was posted on the Frankfurt page. The cruise isn't anywhere near Frankfurt. Luckily, we had a rental car and, so, were able to make the one hour plus drive to the boats.

Super nice tour with an amazing view. The only down side is that due to the schedule we only have 45min to visit Rudesheim.

This tour is so bad it's practically a scam! For 1, it's only 17.50 euro to get a ticket at the window. So you're basically paying double getting it here. Second, hop on hop off is incredibly misleading. I hopped off at one stop and no boat ever came back to hop back onto. The castles are all focused in the center of the cruise path too, so if you're coming from the cruise's starting point, you'll be lucky to have enough time to see 1 castle.

This was horrible and not what it says it would be. There wasn't go on hip off privileges.
