After years of reading the thoughtful advice here, I have my own question. My husband and I are going to France in late September for 9 nights. Our tentative plan is 5 nights in Villafranche-sur-Mer (we got a fantastic Airbnb so are happy to take our time exploring the area) followed by 4 nights in Paris. However, this will be our fourth visit to Paris, and we love it, but seems like we should consider trimming a couple nights from Paris and see somewhere else in France.
Where can we easily fly or train to from Nice and then to Paris, to spend a couple nights and ideally do a small group wine tour on the full day. Lyon seems to be one option, would love to hear what others might recommend. We did a day trip to Reims from Paris a few years ago and enjoyed it, but my husband is looking for something different.
