Something that I've thought of doing for parties but haven't put to the test yet is High-Quality Dried Food. I love playing guitarists and one of the reasons a lot of Sims stop throwing tips at a guitarist is because they get hungry and leave. So, that was my thinking is just always having high quality dried food in the Inventory and just put it on the ground in front of the Theatre. So, I think that technique would work for any party. Yes, it's kind of bizarre, but hey — whatever works, right?
