I think I will follow your suggestions of Order only.
Heres the ideas so far of what the roleplay will consist of:
Ball dancing
People discussing things over drinks
Billiards (I am trying to figure out a way of making this interactive)
Darts
Perhaps a fight may break out
Card games
Speeches maybe
Video screenings
Again, I am trying to make the games interactive, but I may just end up leaving everyone to just improvise the RP. Alternatively, I can ask certain community members to lose or win, or make new characters temporarily to fill some RP holes.
And it does look like this will probably be a Watering Hole type thing, but probably in the story thread since it will eventually end.
