1. If you think you know where you are, you're probably holding the map upside down.
2. Apparently it is possible to feel seasick on the tiny vaporetto ferries.
3. When asking for directions, remember that 'straight ahead' (sempre dritto) will never ever actually mean straight ahead. What straight ahead actually means is 'go through a series of wiggly allies all going vaguely in one direction'. Can't miss it.
4. Good shoes!! Good shoes are essential in Venice. I feel like a fashionable idiot and my feet hurt.
5. Just because a massive slice of pizza costs €2 at Pizza Al Volo in Campo Santa Margherita, does not mean that it is a cheap lunch. You will go back. Many times.
6. Street names and addresses mean nothing here. If you're lost, you're better off asking for directions to a big landmark (like Rialto Bridge or San Marco) and just knowing your way from there.
7. Spritz, the bright orange alcoholic drink that everyone has here, is sharp, bitter and not very nice. It's cheap and popular in Venice, so try it once, then leave it out.
8. Speaking of drinking, student bars near Ca'Foscari University are hugely preferable to tourist bars on the main drags. More authentic, and a medium-sized glass of wine is usually around €2.
9. Fritelles are incredible. They're little Venetian dougnuts which are entirely made of happiness and calories. They're especially tasty from the better bakeries, where they're made with pine nuts and raisins.
10. People talk about food a lot here. I went to a dinner party with my host family, and the guests talked about regional foods, Italian delicacies and recipes for an over an hour. It was fantastic, and made me realise how little I know about cooking.
