We were also on the 16 July transfer to Venice. Our flight departure was 1310 we boarded our bus appr. 0730, was only half full. I hope I never have to fly out of Marco Polo again, what a zoo, Toronto by comparison is a well organized operation. After finding the AC desk which took a bit, them trying to find were security check was, there are different ones, after clearing security you then walk through a very long duty free shop to get to the customs clearing check point. After that you find your gate. There are very few places at the gate to try & find something to eat, they are all behind you in the duty free shop, what a mess. Your bus times are based on your flight times, we had lots of time.
