In a large pitcher, combine pineapple juice, orange juice, cranberry juice, and lime or lemon juice. Stir gently to mix.
Taste and, if needed, add honey or simple syrup to sweeten slightly. Stir again.
Refrigerate the juice mixture for at least 1 hour to chill.
Just before serving, gently add the carbonated water to the juice blend. Stir carefully to keep the fizz.
Add ice cubes or frozen fruit and garnish with fresh fruit slices.
Serve immediately and enjoy your refreshing homemade fruit punch soft drink!
