Can I change the balcony room after Caesar's cruise ship gets on board?

if it is necessary to change the room type, it is recommended to confirm with the booking travel agency whether it is possible to change it before going out. If it involves changing the room type after boarding the ship, it is complicated and may not be possible to change it, because it involves the selling price of the original room type and the new room type. If there is a spare room to allocate, you should pay the money on the spot and change the room card at the reception desk.
