Sugar Free Punch Recipes Please

I am hosting our local WLS Christmas party and really need a great sugar free punch recipe. Last year I used Minute Maid raspberry punch with diet sprite and a little cranberry juice. Does anyone have something else I can serve?

Here is the punch that I serve at our support group Christmas party every year. I think if I ever changed it there would be some very upset people. 1 bottle light Hawaiin Punch 1 bottle Dt. Ruby Red Squirt 1 bottle Dt. Sprite or 7-up Mix together in punch bowl and add scoops of NSA Vanilla Ice Cream on top and stir together. You could also freeze some cranberries and oranges in and add to it for a more festive look.

Do you let the sodas go flat first or use the fully carbonated? I am only 3 months out and haven't yet braved the bubbles Thanks, Rachael
