Very difficult to use. I was interested in finding a special place such as a castle along the Rhine River to stay and celebrate our anniversary. Since the book included a Rhine River itinerary and included "Exceptional Places to Stay" in its title, I thought this would be a great resource. Unfortunately, there appears to be little relationship between the itinerary section and the hotel section. Flipping through Map 2 which appeared to include the Rhine Valley (map was basically useless), it was impossible to determine where the hotel was without looking each one up.
