What train stop?

My roommate and I went to meet my parents for part of their journey through France. We knew they were going to Chenonceaux so we planned our train tickets to go there. But then I figured out at 2 am the night before we were going to leave that the place we were supposed to meet them, the Villandry Gardens, were outside of Tours instead of Chenonceaux. The tickets to Tours were 71 euro and the ticket to Chenonceaux was 41. Ugh. So we got tickets to Chenonceaux. But, at our first change of trains, we were getting on a train going to Tours. We made an executive decision to stay on the train and head to Tours instead of changing trains in Chenonceaux. Thankfully we sat right next to the ticket guy, so after he checked our first tickets he didn't bother to see if we were still supposed to be on the train later on down the tracks. We got to Tours 2 hours earlier than we would have gotten to Chenonceaux. Woo for making it cheaper and earlier than we thought! Sometimes it is just better to stay on the train.
