Yeah I think throwing a party would be a little boring. I'd rather let you guys find a good way to introduce characters yourself (and potentially let you react to newcomers to the town).
Whoops >_< Well, I was intending on letting a few people post first and get acquainted because having something to do...although the dinner would be a little funny for the aftermath.
You can make a post of what your character was doing earlier in the day, though. You don't necessarily need to interact with others in your opening post.
