Labeling cups during parties

When having a big party and you plan to use disposable cups, it’s a neat idea to ask guests to label their cups so they don’t get mixed  up with everyone else’s.  This also minimizes the changing of cups every time guests get a re-fill.  I know disposable cups aren’t enviromental-friendly, but if you do decide to use some occasionally, at least  this tip would help you keep usage  at minimum.
