I agree with Shirley. As soon as I figured out that one of my girls was a boy and removed him from the sorority, I had no problems at all with my girls. I even added a new girl without the recommended rearranging, and the rest of the girls just acted as if she'd been there all along! So, even though some have bad experiences, others have really good experiences.
I also agree about the sorority decorating disease! I have it bad. Any time I go into a store, I think, "ok, what would be safe in a fish tank and look cute?"
I have martini glasses, a glass sculpture, small glass cups for caves (colored glass), river rock arches that I made myself, and the list goes on! So don't worry if its a little bare now, give it time! haha!
