Fill two ice cube trays with water, then divide the festive ice ingredients among them. Freeze until solid.
Once ice is solid, make the simple syrup by combining sugar, water, cinnamon sticks and fresh ginger in a small saucepan. Set over medium low heat and bring to a simmer. Once simmering, cook for about 5 minutes, or until the sugar has dissolved. Remove from heat and cover the pot and let it infuse for at least 30 minutes. Once infused, strain the syrup into a clean bowl (discard cinnamon and ginger) and chill in the fridge until cool.
When ready to serve, in a large punch bowl, combine chilled simple syrup, orange juice, cranberry juice, pomegranate juice and orange slices. Add festive ice cubes.
Set out additional ice and club soda on the side. Serve punch individually over ice with a splash of club soda, if desired.
