I'm sorry I don't have tips on making more rooms, but I have to say that I think the girls sharing a room is a great idea. I worked in student services at a university before I stayed home with my son, and freshmen at universities and colleges everywhere are having an awful time adjusting to dorm life because they've NEVER had to share a room. I think it's a great learning experience for the girls, it will make them closer, and they'll be able to comfort each other if they have bad dreams, etc.
