Hello, the boarding procedures usually start 3 hours before departure. You need to provide your valid identification documents, such as ID card and passport, to the cruise control desk. If your child does not have an ID card, you can use the household registration book. The cruise control desk will arrange a room based on the passenger situation of the day's voyage. You will also receive the room number and room card, and be informed of some arrangements and precautions on board. Thank you for your attention to theMeiya Three Gorges Cruise Ticket BookingCenter. Wishing you a happy life.
