I don't think this expansion so much focuses on a party aspect, although that is part of it, but more on making social clubs with your sims. To be honest since completing my dynasty I haven't thrown a single party, lol not even to try out the new stuff in Spooky Day (or whatever that pack was called) so I probably won't be using the party function with this pack either, apart from the occasional dance party I guess, as I want to explore the dance/DJing side of it all. I'm more interested in the new cafes and being able to hit the swimming pool etc with my sims than throwing parties. I think there is quite a difference between hosting a party and hanging at a place with a group of friends, just this kind of gets a bit blurred when we think about the sims.
In fact, in many ways this expansion pack gives simmers like me, who hate partying, another way to have our sims socialise with their friends without having to throw parties all the time. I'd much rather have my sim in a swimming club or a gym/fitness club and spend time doing that than throw a Black and White party! Least now my sims will be able to build their fitness skill, socialize, earn club points for club rewards, work on their fitness aspiration etc etc all at once instead of having to stand around doing random party goals.
