How long will the Yangtze Cruise take?

Hello. I will take the Yangtze Cruise, which has been recommeded by my friend. He took that tour and found it well woth the visit. But at first, i would like to know how long will it take? how many days?

There seem many different sections of Cruise, but not sure. I only know the tourist-beaten section:chongqing-Wuhan or vice verse and it probably takes you 4 or 5 dyas.

[size=2][font=arial]It depends on which sections of the river you to visit. Currently, the cruise ships sailing 4-5 different routes:[/font][/size] [size=2][font=arial](1) Chongqing - Wuhan or vice verse. This is the most popular section. It usually takes 4 days 3 night downstream and 6 days 5 nights upstream.[/font][/size] [size=2][font=arial](2) Chongqing and Shashi (or or Jingzhou). This section usually takes 3 day 2 night downstream and 5 days 4 night upstream;[/font][/size] [size=2][font=arial](3) Some ships are sailing just the Three Gorges section, between Chongqing and Yichang. It usually takes 4 days 3 night upstream and 3 day 2 night downstream. [/font][/size] [size=2][font=arial](4) A few ships are extending the itinerary from Chongqing down to Shanghai which makes a 10-day itinerary. [/font][/size] [size=2][font=arial](5) A small number ships are sailing Yichang-Fengjie-Yichang. It takes 3 days. But those smaller ships sail on such an itinerary only in the wintertime.[/font][/size]
