It's easy to make this cocktail for a group. First, pour six cans (about 2 liters) of Cranberry Sprite into a punch bowl or drink dispenser. Then add 14 ounces of cranberry juice. To add some pizzazz, float fresh cranberries and rosemary sprigs in the drink. For an extra special occasion, you can make an ice ring as a fancy garnish.  Freeze a few inches of water in an angel food cake pan or small bundt pan and add fresh cranberries to it.  To release it from the pan, set it in warm water for a few seconds, then turn it out into the punch bowl.
