We are researching getting to Florence after we arrive in Bologna. There is a shuttle bus from the airport to the train station, where you can then catch one of several classes of train to Florence - they all seem to take about an hour, some a little longer. We also found a site earlier today that has private cars for hire (with a driver). We have an email into them asking for a price. I have a feeling it is going to be much more expensive than the train, but if it is close we are leaning this way. There are 4 of us, and we are going to have a lot of bags - it would seem a lot easier to hop into a car and get taken door to door, especially with the kids, than lugging around all the luggage from the airport to the bus to the train to the taxi, etc.
