We had a great experience with Bike Tours. Positive: good communication pre trip and the night before. Good pre-trip description of the hotel locations, hotels, and what to expect from the bikes. Night prior, very good review of what to expect. We rented the premium bikes and glad we did--worked very well. On the tour, very good ideas of what to see, and the distance between towns seemed to be well thought out with the first and last legs the shortest. Hotels were great. A diversity of new and classic and all had more to them than what I expected. Often ate at the hotel restaurants which were very good.
On the negative side, not much. Directions into and out of town accurate except the last leg going into Vienna -- on that one Google maps was much better.
We will definitely do another trip with Bike Tours and even this exact one-- it was memorable and fun and want to experience it with more friends.
