Pour in 2 ounces of cranberry juice into each glass.
Top off each glass with lemon-lime soda.
Garnish with lemon slices and maraschino cherries.
Stir gently and serve immediately.
Notes
Adjust the amount of vodka to your preference. For a non-alcoholic version, omit the vodka and increase the amount of pink lemonade and lemon-lime soda.
