I'm in the planning stage.
Borrowed a proper disco ball - just got to figure out how to attach to ceiling of the hall.
Going to make a disco ball cake (my fav bit) & neon/silver cupcakes.
Sparkly fabric for tablecloths and to make party bags with.
Will borrow as many twinkly lights as possible.
Bubble machine.
Glow sticks & LED flashing balloons which can be taken home.
Games - dancing obviously, limbo, conga ????
What else? Budget pretty much spent on the above so any other ideas for cheap/free additions needed.
