Place 1 (2-gal.) zip-top plastic freezer bag inside another 2-gal. zip-top plastic freezer bag.
Place bags in a large bowl.
Combine cranberry juice, limeade, and lemon-lime soft drink in the inside bag. Seal both bags, and freeze 24 hours. (Double bagging is a precaution to avoid spills.)
Remove mixture from freezer 1 hour before serving, squeezing occasionally until slushy.
Transfer mixture to a 2-gal. container. Stir in fruit.
