Any Ideas?!

Hey guys. My name is Katrina, i`m from West Chicago High School, and our theme for prom is going to be "Let the Good Times Roll" (casino night). And the seniors this year are saying how our prom is going to suck and that theirs was better... So we want to make ours so much better than theirs, so right now we have a balloon drop, some sweet decorations and just some other stuff... Do you have any ideas that would make our prom AMAZING??? thanks for your help!
