Hello, according to the regulations and booking agreement of Three Gorges Cruise Company, the cruise ship will allocate rooms based on the room type at the time of booking when you board. Sometimes, when a more upscale room becomes vacant on a cruise ship, the service staff may recommend it to you and you may consider paying the price difference for a replacement. But if you order a high-level room and want to lower the level after boarding, it will not be allowed. For rooms of the same level, the reception desk of the cruise ship is also randomly assigned. If you are not satisfied with the location of the assigned room, you can coordinate with the front desk staff. If the room allows, priority will be given to replacement. If there is a floor price difference, an additional price difference will be required. Thank you for your attention to theMeiya Three Gorges Cruise Ticket BookingCenter!
