Gondolas, of course, are a big part of what makes Venice special. Popular and numerous as they may be, they're far from the one only boats on the canals. One of the games we enjoyed playing with our sons was trying to spot new types of watercraft. Ambulance boats, garbage boats, package delivery boats, bus boats (the famous vaporetti), and more all ply their trades up and down the canals. The world is so different when there are no roads!
