Awesome tour with amazing tour and very experienced and knowledgeable tour guide

the rhine valley scenary was very pretty,but the missed the heidelberg,

This was one of my fav tours I took. The Rhine valley is amazing.

It was a very enjoyable tour

We were a party of 4 and we definitely expected much more than what we got. Out of 11 hrs, we spent around 6 hrs on a bus! Only 1.20 hrs on a boat. We would not recommend this tour.

This was a great trip. The weather was perfect and our guide Adrian was excellent. Our driver Alex did a great job of getting around the very narrow streets and avoiding cars...especially one going the wrong way. We did Heidelberg then the Rhine River cruise and dinner, and wine tasting. It was lot of fun and I would do it again.

First, the tour was not what it was advertised to be. The bus driver was on of the worst drivers ever. Dozing off, all over the rode, nearly crashing into other vehicles. Had to wake up the tour guide to ask if the driver was under the influence. One of the scariest bus rides I have ever been on. The wine tasting was a joke, they gave a size taste of wine. I would never book another tour through them. 1/2 star for the tour guide who was knowledgeable.

It was an 11-hour day but unfortunately 6 hours of that was spent on an old, poorly-equiped bus. The trip to Heidelberg wasn't too bad - 1.5 hours but the the on-bus toilet was not operational. The tour guide Adrian was poorly presented scruffy old clothes, hair and not even an identifying badge. It seemed he and the bus driver Alex had their own deals going to avoid parking the bus in designated areas so we had to wait for pickup at two different spots in Heidelberg.
The real problems began when we left Heidelberg. We diverted to pickup two more customers in Heidelberg, with the bus going down side-streets and getting stuck, having to reverse etc. We lost about 45 minutes. Then we were told by the guide the bus would take us back to the office in Frankfurt to drop off some customers and pickup others for the boat ride. It seemed the company just strung together two tours at their convenience not ours. We got off the bus in Frankfurt after a further 1.5 hours no bathroom break again! and got straight back on for the transfer for Kaub. This took a further 2 hours, all the while the guide telling us there was a possibility we might miss the last boat departure scheduled at 5pm. Thankfully they held the boat for 20 minutes so we got on. The boat cruise was good but light was fading fast. At the restaurant we were served a choice of a quarter chicken and fries or vegetables and fries - very poor. We moved to another room for a quick wine tasting that consisted of 5 plastic thimbles each with a splash of wine. It was embarrassing. We then got back in the bus for our return to Frankfurt that was then diverted to the cargo area of the airport to drop-off the two customers who had a car transfer back to Heidelberg. We have taken many Viator trips around the world - and never had such a terrible experience. A very bad way to end our stay in Germany and a waste of money.

Guide was great and I appreciated the effort to jam both events into one day, but both things could easily take up the better part of a day. Also there should be an option to pay less if you do not drink, which I do not.
