Shake together everything but the club soda with ice. Pour into a pint glass* with 2-3 ice cubes. Fill with club soda.
* Needs to be roughly that volume, but a tiki-style mug would be thematically appropriate.
Variants: You can also make this with 1 oz Don's Mix if you want a more cinnamon-forward flavor, but this version is more balanced.
You can garnish with anything appropriate to Tiki drinks if you want. I'd probably do an orange wheel and a mint sprig.
