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.
