Disable game features such as the welcome wagon and vampire break-ins

Having vampires break in is one reason I haven't bought that particular expansion, which is a pity because I would really have liked some of the objects included with that particular pack. The welcome wagon isn't too bad for me although it can be annoying. I discovered that you can cancel it anytime by clicking on it to end early, but what annoys me most is that darned fruit cake which makes my sims uncomfortable. I say, get rid of the fruit cake!
