If I am staying 1 night in Tours, and want to visit both Azay le Rideau and the Abbey Fontevraud (Fontevrault, same place?) in the same morning (can't go longer than 1 morning, have to catch the train to Chartres that afternoon), how do we do it by public transport? (no car, just train or bus, there and back to Tours, please?). Rolling a couple new spots to visit around in my mind....
