I'm planning my first (maybe last) trip to Paris. We'll be spending most of the week there but i want to get out and see some of France while I'm there. The Loire valley was recommended to me. Im looking for a smallish town with good food, laid back atmosphere that will still allow us to see a liitle bit of this pretty area. We'll be arriving by train from the airport on a Saturday and leaving Monday afternoon for Paris. What location would be best?
