Everything went very well, we had a wonderful time! We were able to find the correct location for the beginning of all of the guided tours, and they all were very informative and interesting. The driving tour was a real hit for us, as we loved seeing the countryside and getting out of the crowds and stone of the city.
The only minor thing might be the boat tour in Florence. You referred to this as a "cruise", which I think makes it sound bigger and fancier than it really is. It was still a lot of fun, but a different wording I think would set more appropriate expectations.
Thanks for facilitating this for us.
