The bus trip and tour to Castello del Trebbio was terrific after we found the bus. There were no clear directions on where the bus would be parked in Florence. The street name provided is a very long street with many buses and adjacent to the train station where lots of buses are coming and going. When we finally saw a bus with a small piece of paper in the window that read "Wine Tour," we hailed the driver and were told it was not the right bus. With only a few minutes left before we would miss the tour, we were so upset, but we learned that it was, after all, the correct bus. We joined several other very frustrated travelers who also could not determine the correct bus. We thoroughly enjoyed the castle tour and wine tasting. Our tour director did a great job, and the tour of the castle and winery is well done. However, better instructions on finding the bus and larger signs earmarking the correct bus would alleviate a lot of frustration experienced by those who book your tour.
