Mix Flavors: In a large pitcher, combine pink lemonade, pineapple juice, cranberry juice, and light rum (if using). This creates the base of your punch with a delightful blend of sweet and tart flavors.

Chill and Refresh: Add a generous amount of ice and stir well to chill the mixture.

Add Fizz: Just before serving, top the punch with sparkling water or soda to add a refreshing fizz.

Garnish for Festivity: Decorate with fresh fruit slices like pineapple, orange, or cherries to enhance the visual appeal and add a touch of tropical flavor.
