Pineapple-Peach Punch

Whisk together pineapple juice, cream of coconut, peach nectar, and apricot nectar in a large pitcher. Divide pineapple mixture among 3 (2-gal.) zip-top plastic freezer bags, placing one-third mixture in each bag. Seal bags, and freeze 2 to 3 hours or until slushy. Remove bags from freezer, and let stand 5 minutes. Pour pineapple mixture into a large punch bowl; stir in chilled vodka, and top with chilled club soda.
