If you enjoy playing with vampires, as I do, I recommend two mods. They are both available from Monique on Mod the Sims. One is the coffin caller, which automatically calls your sim to their coffin at 7 AM and keeps calling them until they go. If something gets in their way, instead of dropping it from the queue as it normally does, they will try again until they get there. The second is the Vamp daytime indoors hack. Makes it so that as long as they are indoors, their motives decay slowly.
I also have vamp friendly careers I got from that site. They don't fulfill career LTWs, but they give your Sims a job to do.
