Hello, the Three Gorges cruise ship's launch itinerary refers to Chongqing Yichang, and the water supply itinerary refers to Yichang Chongqing. The launch usually takes 4 days and 3 nights, and the water supply usually takes 5 days and 4 nights. Usually, due to limited travel time, some tourists choose a 4-day 3-night diving trip, resulting in tight sales of some diving tickets. Therefore, the pricing of boat tickets by cruise companies may be slightly higher. Tourists who choose to travel by water or sewage have no impact on the scenery along the way, and can choose a suitable travel time to consider the route.
