We are traveling to Italy with two other couples at the end of March. Part of out trip is to be based in Siena for 5 days. We are hoping to do this portion without a car and are looking for activities and side trips. We are hoping to do a one day cooking class, a trip to Montepulciano/Pienza/Montalcino maybe with a local guide, possibly a winery visit to Chianti that would include a wonderful lunch. Any suggestions of recommendations for these or other experiences would be much appreciated. Due to the fact that we have a group of 6 it seems easier to do small group escorted activities rather than rent a car (we will also be able to enjoy the wine knowing we won't have to drive!)
