Las Vegas sweet sixteen ideas?

I am throwing a sweet sixteen with a Las Vegas theme. I need ideas for decorations, and centerpieces for the party. So far i have the Las Vegas sign at the entrance, giant dice and playing cards. I don't know what to do! I also want some of the famous hotels to be the centerpieces for the tables (Luxor, Bellagio, Caesar's Palace, etc) but i have no idea what I should do with that idea for the centerpieces.
