A must see if vising Venice and so glad we reserved a time on line costing 1.5 euros to avoid the queues. When we got there the queue was horrendous, but we just walked right past and straight in no problem. TIP .. take something to cover your shoulders, they charge 2 euros to give you some sort of paper cape to cover you otherwise, bit cheeky we thought. I'd taken a very tiny t-shirt which I could crush into my bag and just slipped this over my shoulders as we entered and no one bothered us. Also watch out for the shop as you leave - we bought a glass gondolla but found it was broken (in the box) when we got back to the hotel.
