Garnish with a lime slice, maraschino cherry, and/or cranberries, if desired.
Notes
Cranberry juice: There are three choices for cranberry juice. If you like a cocktail that's tangy, use unsweetened 100% cranberry juice. If you prefer things a bit sweeter, use 100% juice cranberry blend (no sugar added), which is cranberry juice mixed with apple, grape, and pear juice. The sweetest option is cranberry juice cocktail which has added sugar. I usually use the unsweetened cranberry juice blend.
With a cocktail shaker: Instead of serving this cocktail over ice, put all of the ingredients into a cocktail shaker, shake for 15 seconds, or until chilled, and then strain into a glass to serve.
Make a pitcher (make ahead): To make a party-sized batch (8 servings), mix 2 cups vodka, 3 cups cranberry juice, and 3 cups pineapple juice in a large pitcher. This mixture will keep for several days in the refrigerator. Stir well before serving over ice.
Variations: Substitute coconut flavored rum instead of vodka to make a Malibu Bay Breeze. To make a Sea Breeze, replace the pineapple juice with grapefruit juice.
