Add the ginger, unsweetened cranberry juice, orange juice, lime slices, orange slices, and cranberries to a large non-reactive bowl and gently press with a potato masher or wooden spoon to release the juices. Stir to combine and place in the refrigerator to chill for a few hours.
Remove from refrigerator and strain to remove solids, squeezing out excess liquid from the sliced fruit in the process. Discard solids and transfer remaining liquid to a large pitcher.
Add chilled club soda (and vodka, if using) and stir to combine.
Serve immediately over ice and garnish with extra cranberries and/or orange slices. Cheers!
