In large pitcher, stir together coconut water, guava nectar, orange slices and mint. Transfer pitcher to refrigerator until ready to drink.
Right before serving, add soda. Pour into tall glass with ice.
Note: For adult version of Island Punch, stir in 1½ cups rum before refrigerating; substitute lemon-lime soda with 2 cups champagne.
The only catch about chilling down your punch with ice cubes: once the cubes melt, they can water down the flavor of the drink. Next time, try this trick: Pour 2 cans (11.8 oz. each) GOYA® Coconut Water into a freezer-safe bowl. Cover with plastic wrap and freeze until solid, about 4 hours. Then, unmold the coconut water ice and place in a bowl with punch. As this ice block slowly melts, the coconut water keeps the drink tasting great!
