Answer:
They should get two loft beds and put them on either side of the room.
Explanation:
If they get loft beds, their beds won't take up so much room because it'll be in the air. And there is room for both sisters to have a desk/ dresser and space to themselves in their loft. They should have curtains over the bottom part of the loft so that they can have privacy. The middle of the room should be used as a "common area" so they both can do whatever in the middle as long as they clean it up.
Plus lofts are cool.
