I think every cruise line needs to add storage in the bathroom like Carnival has on the Spirit and Conquest class ships. You have 6 shelves in the bathroom which is a lot of room. I have talked to other people that say make sure you bring the shoe organizer for storage for the bathroom, but with Carnical's newer ships you don't really need it.
Also I wish all the ships have what the Spirit class ships have. A nightstand with 3 drawers and there are two in each room. But the only problem they only have these in the interior rooms. They are nice becuse it gives you a lot more drawer space.
