We are currently on Serenity in an ocean view cabin. We have sailed on Serenity before in an ocean view cabin and one of those was the 2015 World Cruise. I know people have said the closet is smaller and it is. I think the bigger problem are the doors. They use to be sliders and you could move them one way or the other to expose the entire closet. The doors now are pocket doors. When they are both open, the door on the right is within a couple inches of being flush with the interior closet wall. The closet wall on the left is two feet from the door edge. It makes it difficult to reach items on the far left side of the closet.
Drawer space is a little less. The vanity used to have drawers on both sides. Now they’re only drawers on one side. The refrigerator use to be above one side of the vanity and that is now next to the closet.
