OK. We're (obviously) having the ball in Anita's castle. Specifically, in a large room inside Anita's castle - maybe the size of a larger school gym but with much better acoustics. It's a rectangle - longer east/west than north/south. The walls, ceiling, and empty sections of the tables are festooned with flowers, mostly springtime ones but with a few poinsettias and such thrown in just because.

In the northeast corner of the room, next to a Harry Potter poster, is the refreshment table, adorned with a bright pink tablecloth. On this table are - well, that's the food caterer's business. Who was that again? Anita? I forget. :(

In the southeast corner, next to a Backstreet Boys poster (only those two posters, don't worry) is a second table. This contains the main CD player (although speakers are placed at equal intervals along the walls, this is where you choose what music to play) a microphone in case you have any announcements, and a disco ball. (Oooooh... colored moving lights... oooooh... pretty...)

The rest of the east half of the floor is bare and that's where you're supposed to dance.

And what did I do with the west half, you ask? That's simple enough. With the extra $35 galleons given by charitable people I can't remember the names of, and the fact that everything's much cheaper because Anita has unpaid house elves, we were able to install a swimming pool.
