This was our first bike tour as a family, but based on our experience, it won't be our last. Overall, everything went smoothly and was great!! BikeTours was responsive to my many questions and easy to work with. The representative from the tour company brought the bikes and documentation as expected, and was flexible when one bike didn't fit correctly (our error) and needed to be exchanged. Service at every stop was very good to outstanding, and the accommodations were very comfortable and clean without exception! Our luggage was smoothly transported from one day to the next. The bikes were comfortable, and riding along the Danube was really special!
I agree with another reviewer who suggested reading through the touring documents each evening to decide on where to stop the next day. That worked well for us too. We also brought snacks and water, and made a point of stopping regularly, given particularly warm weather. I would also recommend having at least one phone with a GPS application, as finding the specific hotels was sometimes challenging, particularly in the larger cities.
Biking through small cities and towns provided a different type of vacation experience for us, as we are used to visiting larger cities. We really enjoyed seeing the country in this way. I found a few of the longer days of biking to be challenging, but as promised, the path was flat to slightly downhill and we were on bike paths for the majority of the time. Even in Vienna, there were bike lanes in the city to get us to the hotel. The paths were well traveled and always felt safe.
Overall, everything was great and I would do it again in a second!
(There were 4 of us traveling...my husband, me and our 2 children in their early 20's. We really liked the flexibility of being self-guided.)
