In a very large pitcher or punch bowl, combine the chilled white grape juice, pineapple juice, cranberry juice cocktail, and fresh lime juice.

Stir the mixture gently until all juices are thoroughly combined. Taste and adjust sweetness or tartness if necessary (you could add a splash more lime juice if desired).

Refrigerate the juice base for at least 2 hours if not already completely chilled, allowing the flavors to meld.

Just before serving, slowly pour in the chilled lemon-lime soda or ginger ale. Stir very gently once or twice to incorporate without letting all the carbonation escape.

Ladle the punch into individual glasses filled with ice. Garnish each serving with a few frozen raspberries and a thin lime wheel on the rim.

For a festive look, add a few extra berries or lime slices directly into the punch bowl.
