THE Party Punch

This was very good.  I made it exactly as they said to here.  It was tasty and not overly sweet.  But I didn't think it would be awful with regular 7-up.  It probably depends on what you are used to.  But it was definitely a hit.  Thank you Pinterest.  I think I may try this with Club Soda some time.  It is tasty, but I don't like using sugar-free drinks.

1 can frozen piña colada concentrate, thawed (Bacardi makes a good one)
1 can frozen orange pineapple juice concentrate, thawed
4 liters of diet lemon-lime soda (That’s two 2-liters for the mathematically challenged.)
1 bag of pebble ice (You can buy it at Sonic Drive-In or at most grocery stores in the deli or meat departments.)
1 bag of frozen raspberries
Directions:
Pour the thawed concentrates into your punchbowl and stir.
Use one of the empty cans and fill it with water four times and add it to the mixture. Stir.
Add your diet soda to the mixture. (You can use regular sugar-filled soda if you want, but I think it gets too sweet and you will also feel guilty when you fill your glass for the sixteenth time. Which you WILL.)
Next, add about half your bag of pebble ice.
**Please do not insult The Punch by using crappy ice cubes from your freezer. The Punch will hate you forever.
*** Please do not screw up the order and add the ice before the soda. You will get an ugly foam at the top of your punch bowl.
Add your frozen raspberries to the top.
