Read what other Viator.com travelers think about the KD Rhine Pass from Mainz. What they loved, what they liked and what they think could be improved, it's all here to help you make the most of your next trip.
On your web site and the Voucher I printed out it it says there are two boats leaving from Mainz to Colonge. One at 8:45 and another at 9:45. What it fails to tell you is that if you do not catch the 8:45 boat the 9:45 boat only goes to Boppard so either you have to stay in Boppard or take a train to Colonge or further up the river to try and catch one of the other boats which is what we did. Your website needs to be clear with costumers about what they are getting. We are not the only ones that had this issue. There were about 12 other passengers that had this problem. This trip cost me way to much for all the headaches I had to deal with. It was supposed to be a pleasant experience. Far from it.
