Culture corner
Venice is famous throughout the world. People also call it the “Floating City” and the “City of Water” because the whole city is on the water—there are over 117 small islands and over 400 bridges in this city. One of the best ways to see the city is on a gondola—a traditional boat.

Introducing Venice, Italy
Planning Your Trip to Venice, Italy
When to come
Venice, Italy draws lots of tourists during the popular travel months of May through early October. The 11-day Carnevale di Venezia in February is another time when hotel space and public places are in short supply(供应).
To our way of thinking, the best time for a trip to Venice is from late October to April.
Extensive reading
You may see fog, rain, Venice flooding(洪水), or (rarely) snow from late October through March or April, but mild and sunny days are also common.
Air fares and hotel prices are the lowest in winter---- which means you can stay in Venice for a longer time and give Venice the time it deserves(值得).
Where to stay
Venice has hundreds of hotels, B&Bs, and hostels(旅舍). However, most are quite small by mainland standards (标准), and it can be difficult to find a room during the high season or on holiday weekends, so it pays to book early.

Extensive reading
How to arrive
Don’t drive to Venice unless you have to. Parking is
expensive, and finding a place in a garage or outdoor lot can be difficult in the high season.
Train service to Venice is frequent. Just be sure that you’re booked to Venice's Santa Lucia Station, not the mainland station of Venezia-Mestre.
Major airlines connect London, Amsterdam, Frankfurt, and other European gateways to Venice’s Marco Polo Airport.
Think: What do you think is the best time to visit Venice
